Q1.

In a study of pain relievers, 100 people were given product A, and all but

35 experienced relief. In the same study,

50 people were given product B, and all but

21 experienced relief.

Fill in the blanks below to make the most reasonable statement possible.

Product ?(Choose one- A, B) performed better in the study. That is because ...%

got relief with this product, whereas only ...%

Q2.

We want to conduct a hypothesis test of the claim that the population mean germination time of strawberry seeds is different from 16.1 days. So, we choose a random sample of strawberries. The sample has a mean of 16 days and a standard deviation of 1.4 days. For each of the following sampling scenarios, choose an appropriate test statistic for our hypothesis test on the population mean. Then calculate that statistic. Round your answers to two decimal places. (a) The sample has size 19, and it is from a normally distributed population with an unknown standard deviation. oz=D ot= Q It is unclear which test statistic to use. (b) The sample has size 14, and it is from a normally distributed population with a known standard deviation of 1.2. oz=D ot= Q It is unclear which test statistic to use. Use the ALEKS calculator to solve the following problems. (a) Consider a t distribution with 29 degrees of freedom. Compute P(l' S 1.42). Round your answer to at least three decimal places. P(tS-1.42)=I] (b) Consider a t distribution with 6 degrees of freedom. Find the value of c such that P(-c
