The distribution of heights in a population of women is approximately normal. Sixteen percent of the women have heights less than 62 inches. About 97.5% of the women have heights less than 71 inches. Use the empirical rule to estimate the mean and standard deviation of the heights in this population. Mean: K inches Standard Deviation: inches
SHOW ALL WORK. Interpret confidence intervals and explain the conclusions from hypothesis tests. For all hypothesis tests, clearly state the null and alternative hypotheses, the significance level, the test statistic, the p-‐value, and your conclusion. If you are using a t-statistic, clearly note how many degrees of freedom you have. 1. Consider the following data collected regarding infant blood pressure, age, and birth weight: i Birth weight in oz.

A statistics class is estimating the mean height of all female students at their college. They collect a random sample of 42 female students and measure their heights. The mean of the sample is 65.3 inches and the sample standard deviation is 5.4 inches. Find the 90% confidence interval for the mean height of all female students in their school? Assume that the distribution of individual female heights at this school is approximately normal. 1. The t value is 1.3025 2. The standard error has a value of -- 3. The margin of error has a value of 4. Find the 90% confidence interval for the mean height of all female students in their school
Use the given confidence interval to find the margin of error and the sample mean. (11.3,21.1) The sample mean is The margin of error is
You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Your sample size is 8. While it is an uncommon confidence level, find the critical value that corresponds to a confidence level of 93.5%.

K Large samples of women and men are obtained, and the hemoglobin level is measured in each subject. Here is the 95% confidence interval for the difference between the two population means, where the measures from women correspond to population 1 and the measures from men correspond to population 2: -1.76 g/dL
n1=16 x‾1=124 s1=35 n2=12 x‾2=86 s2=31 Use this data to find the 98% confidence interval for the true difference between the population means. Assume that the population variances are not equal and that the two populations are normally distributed. Copy Data Step 2 of 3 : Find the margin of error to be used in constructing the confidence interval. Round your answer to six decimal places.
