Assume the samples are random and independent, the populations are nomally distributed, and the population variances are equal. The table available below shows the prices (in dollars) for a sample of automobile batteries. The prices areclassified according to battery type. At a = 0.05, is there enough evidence to conclude that at least one mean battery price is different from the others?

A sample of blood pressure measurements is taken from a data set and those values (mm Hg) are listed below. The values are matched so that subjects each have systolic and diastolic measurements. Find the mean and median for each of the two samples and then compare the two sets of results. Are the measures of center the best statistics to use with these data? What else might be better? Systolic: Diastolic: 111 83 53 145 105 149 114 147 134 84 69 90 74 77 122 110 101 73 85 64 Find the means. The mean for systolic is mm Hg and the mean for diastolic is mm Hg. (Type integers or decimals rounded to one decimal place as needed.)
The data table shows the ages in years of 10 men with systolic blood pressure. The Age,x: 18, 26, 39, 46, 48, 64, 68, 31, 58, 22. and systolic blood pressure, y: 111, 123, 145, 130, 201, 183, 198, 131, 177, 119. The sample correlation coefficient r is 0.881. Remove the data entry for the man who is 48 years old and has a systolic blood pressure of 201 millimeters of mercury from the data set and find the new correlation coefficient.

It is generally believed that there is a relationship between a college’s acceptance rate and its graduation rate. I wanted to know how strong this relationship is within the top universities in the country so I collected the graduation rate and acceptance rate data of a randomly selected sample of universities from all the top U.S. universities (with an acceptance rate at or below 30%). The data set is in Tab Q2 of the Excel data file. a.) Create a scatter plot between the two variables using Excel. Paste the plot here and format it into an APA-styled “figure” (see Assignment Guides for APA format).Be sure to submit the Excel file that you used to create the scatter plot. b) Calculate the mean and standard deviation for the two variables separately. c) Calculate the Z scores for all the scores of the two variables, separately.Tips: It may help to prevent error and to increase clarity if the process and/or the answers (z scores) are listed in a table format. d) Calculate…
