Interstate Speeds It has been reported that the standard deviation of the speeds of drivers on Interstate 75 near Findlay, Ohio, is 8 miles per hour for all vehicles. A driver feels from experience that this is very low. A survey is conducted, and for 29 drivers the standard deviation is 9.9 miles per hour. At =α0.10, is the driver correct? Assume the variable is normally distributed. State the hypotheses and identify the claim with the correct hypothesis. H0: H1: Claim or Not a Claim? This Hypothesis test is one-tailed or two-tailed? What is the Critical Value?

You want to obtain a sample to estimate how much parents spend on their kids birthday parties. Based on previous study, you believe the population standard deviation is approximately σ=49.9σ=49.9 dollars. You would like to be 95% confident that your estimate is within 5 dollar(s) of average spending on the birthday parties. How many parents do you have to sample? n =
Medical Operations The director of a medical hospital feels that her surgeons perform fewer operations per year than the national average of 211. She selected a random sample of 15 surgeons and found that the mean number of operations they performed was 210.6. The standard deviation of the sample was 3.8. Is there enough evidence to support the director's feelings at =α0.10? Assume that the population is approximately normally distributed. Use the critical value method and tables.a. State the hypotheses and identify the claim H0= (claim or not claim) H1= (claim or not claim) This hypothesis test is a (one tailed or two tailed) test Critical value(s)= t= (Reject or do not reject) the null hypothesis is there enough evidence to support the claim?
