Question 4 of 30 Question 4 1 points Save Answer A new protein power company claims that the mean time to observe a 10% increase in muscle strength is 7 days with a standard deviation of 5.5 days. A random sample of 25 customers attempted to try this new protein powder. The mean time to find a 10% increase in muscle strength was 9 days. The test statistic was found to be 1.81. Which of the following statements is TRUE? Consider a one-tailed test and alpha - 0.05. O p - 0.035; reject the null hypothesis O p = 0.07; fail to reject the null hypothesis O p - 0.14; fail to reject the null hypothesis O None of the above Question 4 of 30 Moving to the next question prevents changes to this answer.Question 1 Which of the following physical activity assessment methods measures number of steps taken?

Twenty eight older adults with MCI were equally divided into two samples. The memory function was assessed using a MoCA 1 points Save Answer test where higher scores suggest better cognitive function. The MoCA test was administered before and after several days of exposure to the new tool. A specific hypothesis test was used and a test statistics of 2.051 was found. Which of the following is correct? Use a two-tailed test and alpha = 0.05. O MoCA score is the dependent variable and based on the information provided we reject the null hypothesis O The new tool is the dependent variable and based on the information provide we fail to reject the null hypothesis O MoCA score is the dependent variable and based on the information provided we fail to reject the null hypothesis The aging neuroscientist is the the dependent variable and based on the information provided we fail to reject the null hypothesis
