David worked \(7\frac{1}{3}\) hours today and planted I I trees. It takes him about the same amount of time to plant each tree. How long did it take him to plant each tree? It took him ___________. hour to plant each tree.

Answers (1)

Since it took the same amount of time to plant each tree, we divide the total time by the number of trees: \(\frac{7\frac{1}{3}}{11}=\frac{\frac{22}{3}}{11}=\frac{22}{3}\times\frac{1}{11}=\frac{2}{3}\)
Result: It took him \(\frac{2}{3}\) hour to plant each tree.

Below is data collected from the growth of two different trees over time. Each tree was planted in 1960, and the tree's height has been collected every ten years.
What type of function is the growth of Tree A? How can you tell?
What type of function is the growth of Tree B? How can you tell?
Write an equation for each function of the trees' growth over time. For time, you may use x=0 for 1960.
Compare the growth rate for each of the trees.
Compare the starting heights of each of the trees.
When will Tree A's height exceed Tree B's height?

factor in determining the usefulness of an examination as a measure of demonstrated ability is the amount of spread that occurs in the grades. If the spread or variation of examination scores is very small, it usually means that the examination was either too hard or too easy. However, if the variance of scores is moderately large, then there is a definite difference in scores between "better," "average," and "poorer" students. A group of attorneys in a Midwest state has been given the task of making up this year's bar examination for the state. The examination has 500 total possible points, and from the history of past examinations, it is known that a standard deviation of around 60 points is desirable. Of course, too large or too small a standard deviation is not good. The attorneys want to test their examination to see how good it is. A preliminary version of the examination (with slight modifications to protect the integrity of the real examination) is given to a random sample of 20 newly graduated law students. Their scores give a sample standard deviation of 70 points. Using a 0.01 level of significance, test the claim that the population standard deviation for the new examination is 60 against the claim that the population standard deviation is different from 60.
(a) What is the level of significance?
State the null and alternate hypotheses.
\(H_{0}:\sigma=60,\ H_{1}:\sigma\ <\ 60H_{0}:\sigma\ >\ 60,\ H_{1}:\sigma=60H_{0}:\sigma=60,\ H_{1}:\sigma\ >\ 60H_{0}:\sigma=60,\ H_{1}:\sigma\ \neq\ 60\)
(b) Find the value of the chi-square statistic for the sample. (Round your answer to two decimal places.)
What are the degrees of freedom?
What assumptions are you making about the original distribution?
We assume a binomial population distribution.We assume a exponential population distribution. We assume a normal population distribution.We assume a uniform population distribution.

Two spherical objects are separated by a distance of \(\displaystyle{1.80}\times{10}^{{­-{3}}}\) m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result, each object experiences an electrostatic force that has a magnitude of \(\displaystyle{4.55}\times{10}^{{-{21}}}\) N. How many electron did? It take to produce the chargeon one of the objects?

In the vertical jump, an athlete starts from a crouch andjumps upward to reach as high as possible. Even the best athletesspend little more than 1.00 s in the air (their "hang time"). Treatthe athlete as a particle and let be his maximum height above the floor. Toexplain why he seems to hang in the air, calculate the ratio of thetime he is above /2 moving up to the time it takes him to go from thefloor to that height. You may ignore air resistance.
I think I have to use the formula \(\displaystyle{y}\max={\frac{{{1}}}{{{2}{a}{t}^{{{2}}}}}}\) and solve for t. So PSKt=\sqrt{\frac{2y_{max}}{a}}, and then do it again when it isymax/2. But then I get stuck there.

Is statistical inference intuitive to babies? In other words, are babies able to generalize from sample to population? In this study,1 8-month-old infants watched someone draw a sample of five balls from an opaque box. Each sample consisted of four balls of one color (red or white) and one ball of the other color. After observing the sample, the side of the box was lifted so the infants could see all of the balls inside (the population). Some boxes had an “expected” population, with balls in the same color proportions as the sample, while other boxes had an “unexpected” population, with balls in the opposite color proportion from the sample. Babies looked at the unexpected populations for an average of 9.9 seconds (sd = 4.5 seconds) and the expected populations for an average of 7.5 seconds (sd = 4.2 seconds). The sample size in each group was 20, and you may assume the data in each group are reasonably normally distributed. Is this convincing evidence that babies look longer at the unexpected population, suggesting that they make inferences about the population from the sample? Let group 1 and group 2 be the time spent looking at the unexpected and expected populations, respectively. A) Calculate the relevant sample statistic. Enter the exact answer. Sample statistic: _____ B) Calculate the t-statistic. Round your answer to two decimal places. t-statistic = ___________ C) Find the p-value. Round your answer to three decimal places. p-value =

A hybrid course is one that contains both online and classroom instruction. In a study performed at Middle Georgia State University, a software package was used as the main souce of instruction in a hybrid college algebra course. The software tracked the number of hours it took for each student to meet the objectives of the course. In a sample of 45 students, the mean number of hours was 80.5, with a standard deviation of 51.2.
a. Construct a 95% confidence interval for the mean number of hours it takes for a student to meet the course objectives.
