Mateo believes that completely cutting caffeine out of a person's diet will allow them more restful sleepat night. He randomly selects 8 adults to help him test this theory. Each person is asked to consume two caffeinatedbeverages per day for 28 days and then cut back to no caffeinated bevarages for an additional 28 days. During eachperiod, the participants record the number of nights of restful sleep that they had. The following table gives the resultsof the study. Test Mateo's claim at the 0.05 level of significance. Give answers to 4 decimal places as needed.Number of Nights of Restful Sleep in a Four-Week Period15With Caffeine21 2022 24182124202626 2221232723Without Caffeinea) The normal probability plot showed the differences follow a normal distribution and the boxplot showed no outliers.b) Test the claim(1) Determine the null and alternative hypotheses.

I use excel. I do not know what data anlysis toolpak to use, however, to find the answer, t stat, df, P, etc. I also don't know how to word Ho and Ha. Thanks! The data shown below are the initial weights and gains in weight (in grams) of female rats on a high protein diet from 24 to 84 days of age. The point of interest in these data is whether the gain in weight is related to (dependent on) the initial weight. If so, then feeding experiments on female rats can be made more precise by adjusting for differences in initial weights of the rats. Statistically test this with a regression analysis.

The time it takes an employee to package the components of a certain product is normally distributed with ? = 7.5 and ? = 1.5 minutes. As an incentive, management has decided to give a bonus to the 25% of employees who took the shortest amount of time to package the components. Find the amount of time taken to package the components that will indicate that an employee should get a bonus. (Round your answer to two decimal places.) An employee must package components in a time minutes.
