Need the claim, hypothesis, crit value(s), rejection regions, d, Sd, t test, reject or fail to, and conclusion. A researcher claims that a post-lunch nap decreases the amount of time it takes males to sprint 20 meters after a night with only 4 hours of sleep. The table shows the amounts of time (in seconds) ittook for 10 males to sprint 20 meters after a night with only 4 hours of sleep when they did not take a post-lunch nap and when they did take a post-lunch nap. At a = 0.01, is there enough evidenceto support the researcher's claim? Assume the samples are random and dependent, and the population is normally distributed.

Español Ojai is a weather station in the state of California and Seabrook is a weather station in the state of Massachusetts. On one summer day, the noontime temperatures recorded among weather stations in California had a population mean of 25.5° Celsius and a standard deviation of 6.1° Celsius. On that same day, the noontime temperatures among weather stations lat in Massachusetts had a population mean of 32.3° Celsius and a standard deviation of 1.9° Celsius. On the summer day, each state's distribution of noontime temperatures among its weather stations was clearly bell-shaped. At the Ojai weather station, the noontime temperature on the summer day was 39° Celsius, and the noontime temperature at Seabrook was 25°…

1.Determine the test statistic. (Round to three decimal places as needed.) 2.Determine the P-value of the test statistic. (Round to four decimal places as needed.) 3. use 0.01 significance to test the claim
The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies? LOADING... Click the icon to view the table. Determine the null and alternative hypotheses. A.

Using 1% for the significance level, find the conclusion of this hypothesis testing in words using the p-value approach. Follow the questions below. 1) State the p-value and interpret the p-value in words. 2) Using the significance level and the p-value, state the conclusion of this hypothesis testing.
While her husband spent 2½ hours picking out new speakers, a statistician decided to determine whether the percent of men who enjoy shopping for electronic equipment is higher than the percent of women who enjoy shopping for electronic equipment. The population was Saturday afternoon shoppers. Out of 68 men, 24 said they enjoyed the activity. Eight of the 23 women surveyed claimed to enjoy the activity. Interpret the results of the survey. Conduct a hypothesis test at the 5% level. Let the subscript m= men and w= women. What is the test statistic? (If using the distribution round your answer to two decimal places, and if using the t distribution round your answer to three decimal places.) What is the p-value? (Round your answer to four decimal places.) Sketch a picture of this situation. Label and scale the horizontal axis and shade the region(s) corresponding to the p-value. i. ii. iii.
