In how many ways can 7 graduate students be assigned to 1 triple and 2 double hotel rooms during a conference

Population The resident population P (in millions) of the United States from 2000 through 2013 can be modeled by $P=-0.00232t^3+0.0151y^2+2.83t+281.8,0\le t\le 13,$ where $t=0$ corresponds to 2000.

Make a conjecture about the maximum and minimum populations of the United States from 2000 to 2013.
Analytically find the maximum and minimum populations over the interval.
The brief paragrah while comparing a conjecture with the minimum population was 281.8 million in 2000 and the maximum population was 316.1 million in 2013.
We need to calculate: The absolute extrema of the popullation $P=-0.00232t^3+0.0151y^2+2.83t+281.8,0\le t\le 13$ over the closed interval [0, 13].

Explain and give a full and correct answer how confusing the two (population and a sample) can lead to incorrect statistical inferences.

Give a correct answer for this question In order to compare the relationship between two categorical variables, the best inference technique is ?

To find: The ${\displaystyle 95\mathrm{\%}}$ confidence interval for the comparison.

It appears that there is some truth to the old adage “That which doesn’t kill us makes us stronger.” Seery, Holman, and Silver (2010) found that individuals with some history of adversity report better mental health and higher well-being compared to people with little or no history of adversity. In an attempt to examine this phenomenon, a researcher surveys a group of college students to determine the negative life events that they experienced in the past 5 years and their current feeling of well-being. For ${\displaystyle n=16}$ participants with 2 or fewer negative experiences, the average well-being score is ${\displaystyle M=42}$ with ${\displaystyle SS=398}$, and for ${\displaystyle n=16}$ participants with 5 to 10 negative experiences the average score is ${\displaystyle M=48.6}$ with ${\displaystyle SS=370}$.
1. Is there a significant difference between the two populations represented by these two samples? Use a two-tailed test with ${\displaystyle \alpha =.01}$ [use the 4-step procedure]. [Remember to assess whether the assumption of homogeneity of variances is satisfied or not, ${\displaystyle \alpha =.01}$ for homogeneity test].
2. Compute Cohen’s d to measure the size of the effect.
3. Report your hypothesis test results and cohen’s d in APA format.
