The NAEP music assessment scores for eighth grade students are approximately N (150, 35). Find the z-scores by standardizing the following scores: 150, 140, 100, 180, and 230. The percentile score is the proportion of students who would score LESS THAN OR EQUAL TO the score for the individual student. Compute the percentile scores for the five scores.

Nicole has a popular blog about cooking and nutrition and regularly posts articles and videos. She has collected data about the length of time that viewers spent watching two of her recent videos. For each video, she recorded the amount of time (in minutes) that each of 102 viewers spent watching it. The histograms below show the distributions of the two data sets. Each histogram shows time (in minutes) on the horizontal axis and the number of viewers on the vertical axis. The means and standard deviations for the data sets are also given.

Breast-feedingmothers secrete calcium into their milk. Some of thecalcium may come from their bones, so mothers maylose bone mineral. Researchers measured the percent changein mineral content of the spines of 47 mothers during threemonths of breast-feeding.6 Here are the data: -4.7 -2.5 -4.9 -2.7 -0.8 -5.3 -8.3 -2.1 -6.8 -4.32.2 -7.8 -3.1 -1.0 -6.5 -1.8 -5.2 -5.7 -7.0 -2.2-6.5 -1.0 -3.0 -3.6 -5.2 -2.0 -2.1 -5.6 -4.4 -3.3-4.0 -4.9 -4.7 -3.8 -5.9 -2.5 -0.3 -6.2 -6.8 1.70.3 -2.3 0.4 -5.3 0.2 -2.2 -5.1 (a) The researchers are willing to consider these 47women as an SRS from the population of all nursingmothers. Suppose that the percent change in this population has standard deviation 2.5%. Make a stemplotof the data to verify that the data follow a Normal distribution quite closely. (Don’t forget that you need botha 0 and a 0 stem because there are both positive andnegative values.) (b) Use a 99% confidence interval to estimate the meanpercent change in the population
The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 30 hours and the median is 26.2 hours. Twenty-four of the families in the sample turned on the television for 15 hours or less for the week. The 11th percentile of the data is 15 hours. Step 4 of 5 : What is the value of the 50th percentile?
