According to the data, the middle 60% of women will be between 62 and 66 inches tall. Explain how we would arrive at such a conclusion using normal distribution. You are encouraged to upload a picture to support your explanation. Heights of men and women in the U.S. are normally distributed. Recent information shows: Adult men heights: p= 69.6 inches with o = 3 inches. Adult women heights: p = 64.1 inches with o = 2.7 inches.

Available below are amounts of arsenic in samples of brown rice from three different regions. The amounts are in micrograms of arsenic and all samples have the same serving size. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Do the amounts of arsenic appear to be different in the different regions? Given that the amounts of arsenic in the samples from region B have the highest mean, can we conclude that brown rice from region B poses the greatest health problem?

According to the Carnegie unit system, the recommended number of hours students should study per unit is 2. Are statistics students' study hours less than the recommended number of hours per unit? The data show the results of a survey of 11 statistics students who were asked how many hours per unit they studied. Assume a normal distribution for the population. 1, 0.3, 2.7, 0.5, 1.8, 2.2, 2.5, 0, 0.9, 0.2, 2 What can be concluded at the � = 0.01 level of significance? For this study, we should use The null and alternative hypotheses would be: �0: �1: The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is � Based on this, we should the null hypothesis. Thus, the final conclusion is that ... The data suggest that the population mean study time per unit for statistics students is not significantly less than 2 at � = 0.01, so there is…
