Calories consumed by members of a track team the day before a race are normally distributed, with a mean of 1,800 calories and a standard deviation of 100 calories. If a normal curve is sketched using these data, what is the range for 3 standard deviations to the right and to the left of the mean? Group of answer choices 0–3,600 1,700–1,900 1,600–2,000 1,500–2,100

Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Refer to the accompanying data set. Use a 0.01 significance level to test the claim that women and men have the same mean diastolic blood pressure. E Click the icon to view the data for diastolic blood pressure for men and women. O A. H H=H H: H >2 O B. H H <2 H =2 O P. H H =2 H 2 OC. H: HHz Calculate the test statistic. t= (Round to two decimal places as needed.) Find the P-value. P-value = (Round three decimal places as needed.) Make a conclusion about the null hypothesis and a final conclusion that addresses the original claim. H. There V sufficient evidence to warrant rejection of the claim that women and men have the same mean diastolic blood pressure.
