A car company says that the mean gas mileage for its luxury sedan is at least 25 miles per gallon (mpg). You believe the claim is incorrect and find that a random sample of 6 cars has a mean gas mileage of 24 mpg and a standard deviation of 2 mpg. At a = 0.05, test the company's claim.

A bank's loan officer rates applicants for credit. The ratings are normally distributed with a mean of 200 and a standard deviation of 50. If 64 applications are randomly selected, what is the probability that the mean credit rating of these 64 applicants will be between 205 and 275. (Round your answer to 4 decimal places.)

This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability. All work must be shown in order to receive any credit. Please upload your completed assignment here. The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard deviation of 0.25 hours. A sample size of n = 60 is drawn randomly from the population. Find the probability that the sample mean is between two hours and three hours.
A new breakfast cereal is test-marketed for 1 month at stores of a large supermarket chain. The results for a sample of 16 stores indicate average sales of $1,200 with a standard deviation of $180. Assuming a normal distribution set up a 95% confidence interval estimate of the true average sales of this new breakfast cereal (see the last page for the solutions). State the meaning of µ first, and then interpret the interval; you may use the TI-84 t interval option. The answer is 95% (1104.1, 1295.9) 1. If the mean sales of the new cereal are at least $1000 per month, the stores will start selling the cereal for a one-year trial. Should the new cereal get its chance in the cereal aisle for a one-year trial? Explain. Answer number 1

What is the confidence interval estimate of the population mean µ? (Round to three decimal places as needed.) What does this suggest about the use of 98.6°F as the mean body temperature? O A. This suggests that the mean body temperature is significantly higher than 98.6°F. O B. This suggests that the mean body temperature could very possibly be 98.6°F. OC. This suggests that the mean body temperature is significantly lower than 98.6°F.
