Assume that the distribution of heights of young women aged 16 to 22 is approximately Normal with mean μ = 62.05 inches. A random sample of 73 female undergraduate students at a University produced a sample mean height of can be derived from the adjacent chart.

Please help with the areas marked with an X To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical Company obtained the following data on the time (in minutes) needed to mix the material.   Manufacturer         1 2 3   19 29 16   25 27 15   23 32 19   21 28 18 a. Use these data to test whether the population mean times for mixing a batch of material differ for the three manufacturers. Use . Sum of Squares, Treatment X Sum of Squares, Error X Mean Squares, Treatment X Mean Squares, Error X Compute the values below (to decimals, if necessary).     Calculate the value of the test statistic (to decimals)_______x_________.          b. At the level of significance, use Fisher's LSD procedure to test for the equality of the means for manufacturers and . Calculate Fisher's LSD Value (to decimals)______X______

Listed below are pulse rates (beats per minute) from samples of adult males and females. Find the mean and median for each of the two samples and then compare the two sets of results. Does there appear to be a difference? Male: Female: 86 71 54 84 57 95 53 89 53 63 59 72 68 85 87 90 91 88 70 92 77 63 82 53 91 88 94 82 86 64 Find the means. The mean for males is ☐ beats per minute and the mean for females is (Type integers or decimals rounded to one decimal place as needed.) beats per minute.
