- The height of women ages 20-29 is normally distributed, with a mean of 64.2 inches. Assume σ=2.8 inches. Are you more likely to randomly select 1 woman with a height less than 64.9 inches or are you more likely to select a sample of 20 women with a mean height less than 64.9 inches? Explain. LOADING... Click the icon to view page 1 of the standard normal table. LOADING... Click the icon to view page 2 of the standard normal table. What is the probability of randomly selecting 1 woman with a height less than 64.9 inches? enter your response here (Round to four decimal places as needed.)You are interested in testing if there is an association between marital status (married vs. never married) and BMI (quantitative).

- In the US, the average one-way commuting time is 26.4 minutes. Is this different in Atlanta? One survey of 35 Atlanta commuters found an average one-way commuting time of 30.7 minutes. (a) The test statistic is 1.1846. What is the meaning of this test statistic? The average error between different sample results and the hypothesized mean is 1.1846.The current sample result is 1.1846 standard errors above the hypothesized mean. The maximum error between different sample results and the hypothesized mean is 1.1846. (b) Based on the test statistic of 1.1846, what is the p-value to test if the average commuting time in Atlanta is different than the rest of the US? (4 decimals.) (c) On the basis of the above p-value, what can be said regarding a 95% confidence interval for the true average commuting time? The interval contain the value 26.4, because this value .
