Use the data below to test the claim that the weight loss was greater with the low fat diet compared to the low carbohydrate diet. Use a 10% level of significance. Low Fat Low Carbohydrate x¯1=3.9lbs s1=4.2lb n1=51 x¯1=2.6lb s1=5.9lb n1=79 Identify the tail of the test What is the P-value? Will the null hypothesis be rejected? Is the initial claim supported?
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.

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

Mean IQ of Attorneys See the preceding excercie, in which we can assume that for the IQ scores. Attorneys are a group with IQ scores that very less that IQ scores of the general population. find the sample size needed to estimate the mean IQ of attorneys, given that we want 98% confidence that the sample mean is within 3 IQ points of the population mean. Does the sample size appear to be practical?
