Which of the following are true? If false, explain briefly.
a) If the null hypothesis is true, you'll get a high P-value.
b) If the null hypothesis is true, a P-value of 0.01 will occur about 1% of the time.
c) A P-value of 0.90 means that the null hypothesis has a good chance of being true.
d) A P-value of 0.90 is strong evidence that the null hypothesis is true.

(a) False
The​ P-value is about the​ data, not the hypothesis.​ It's likely that​ you'll get a reasonably high​ P-value, but​ it's not guaranteed.
(b) True
(c) False
If the null hypothesis is true then a​ P-value of 0.01 will occur about​ 99% of the time.
(d) False
The p-value is not a probability of an alternative (or null) hypothesis being true or false.

b) True.
c) False. If the null hypothesis is true then a​ P-value of 0.01 will occur about​ 99% of the time.
d) False. This​ P-value solely provides no evidence that​ it's false.

When two targets are presented close together in a rapid visual stream, the second target is often missed. Psychologists call this phenomenon the attentional blink (AB). A study published in Advances in Cognitive Psychology (July 2013) investigated whether simultaneous or preceding sounds could reduce AB. Twenty subjects were presented a rapid visual stream of symbols and letters on a computer screen and asked to identify the first and second letters (the targets). After several trials, the subject's AB magnitude was measured as the difference between the percentages of first target and second target letters correctly identified. Each subject performed the task under each of three conditions. In the Simultaneous condition, a sound (tone) was presented simultaneously with the second target; in the Alert condition, a sound was presented prior to the coming of the second target; and in the No-Tone condition, no sound was presented with the second target. Scatterplots of AB magnitude for each possible pair of conditions are shown below as well as the least squares line for each. a. Which pair of conditions produces the least squares line with the steepest estimated slope? b. Which pair of conditions produces the least squares line with the largest SSE? c. Which pair of conditions produces the least squares line with the smallest estímate of σ?

The average life span of a Golden Retriever is said to be 9.6 years. In a random sample of 15 Golden Retrievers, the following life spans were found:
6.8 10.2 9.5 13 9.9 7.0 8.3 8.9 11.2 10 9.8 13 9.8 9.5 8.7
At a 5% significance level, if we do a complete hypothesis test to test eh claim that the average life span of Golden Retrievers is 9.5, the p-value and conclusion are:
p-value = 0.8187, fail to reject the null hypothesis
p-value = 0.8153, fail to reject the null hypothesis
p-value = 0.8187, reject the null hypothesis
p-value = 0.8153, reject the null hypothesis
