Friendship Motivation Scale for Children (FMSC), a scale de- signed to assess children’s desire for friendships. Two interesting conclusions are that friends generally report similar levels of the FMSC and girls tend to score higher on the FMSC than boys. Boys in the seventh grade scored a mean of 9.32 with a standard deviation of 1.71, and girls in the seventh grade scored a mean of 10.04 with a standard deviation of 1.83. Assuming that FMSC scores are normally distributed, determine the percentage of seventh-grade boys who have FMSC scores within a). one standard deviation to either side of the mean. b). two standard deviations to either side of the mean. c). three standard deviations to either side of the mean. d). Repeat parts (a)–(c) for seventh-grade girls.
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.

3) Estimating the Mean: Unknown Variance a) A student is working on his science fair project concerning the average height of a certain native plant, which he believes is normally distributed. He finds 25 mature plants and measures their heights, and determines the average height to be 10.2 cm (s = 1.2 cm). Construct a 96% confidence interval on the mean height of the plants. .<μ<.
You want to estimate the mean weight of quarters in circulation. A sample of 50 quarters has a mean weight of 5.632 grams and a standard deviation of 0.056 gram. Use a single value to estimate the mean weight of all quarters. Also, find the 95% confidence interval for the average weight of all quarters. Find the 95% confidence interval for the mean weight of all quarters. ___ grams < < ___ grams (Round to three decimal places as needed.)

Part Variability is critical in the manufacturing of the ball bearings. Large variances in the size of the ball bearings cause bearing failure and rapid wear out. Production standards call for a maximum variance of .0001 when the bearing sizes are measured in inches. A sample of 15 bearings shows a sample standard deviation of .014. a. Compute the 90% confidence interval estimate of the variance of the ball bearings in the population. b. Use a= 0.10 to determine whether the sample indicates that the maximum acceptable variance is being exceeded. Use critical value approach. ( Note: You must state null and alternative hypotheses, compute the test statistic, Report the critical Value, and draw a conclusion.
