Before the furniture store began its ad campaign, it averaged 117 customers per day. The manager is investigating if the average has changed since the ad came out. The data for the 14 randomly selected days since the ad campaign began is shown below: 85, 114, 96, 124, 110, 121, 90, 115, 127, 116, 117, 110, 84, 129 Assuming that the distribution is normal, what can be concluded at the αα = 0.10 level of significance?

The length of a movie file that is available for streaming is modeled using the normal distribution shown below. The mean of the distribution is 170.5 min and the standard deviation is 19.9 min, In the figure, V is a number along the axis and is under the highest part of the curve. And, U and W are numbers along the axis that are each the same distance away from V. Use the empirical rule to choose the best value for the percentage of the area under the curve that is shaded, and find the values of U, V, and W. Percentage of total area shaded: (Choose one) 100 120 140 160 180 200 220 240 ( min)

In order to estimate the difference between the average miles per gallon of two different models of automobiles, samples are taken and the following information is collected. Sample Size Sample Mean Sample Variance Model A a. 65 26 16 Model B 45 28 a 9 At 95% confidence, develop an interval estimate for the difference between the average miles per gallon for the two models. Is there conclusive evidence to indicate that one model gets a higher miles per gallon than the b. other? If yes, explain how you know this and which model is higher. If no, explain how you know that there is not enough evidence.

The Ford car company is interested to know what is fuel consumption rate of its vehicles A large data set, collected in this study, shows that in average cars 11.7 liters per 100 km distance covered. The standard deviation of this value is 1.3 km per 100 km. Assuming that the histogram of this data set is normal, what percent of cars consume between between 10.5 to 11.9 liter of fuel?
Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD. A random sample of 59 women between the ages of 41 and 45 with no major health problems were studied. The women were classified into one of two groups based upon their level of exercise activity: walking women and sedentary women. The 39 women who walked regularly had a mean BMD of 5.96 with a standard deviation of 1.22. The 20 women who are sedentary had a mean BMD of 4.41 with a standard deviation of 1.02. Which of the following inference procedures could be used to estimate the difference in the mean BMD for these two types of women
