Use the accompanying data set on the pulse rates (in beats per minute) of males to complete parts (a) and (b) below. LOADING... Click the icon to view the pulse rates of males. a. Find the mean and standard deviation, and verify that the pulse rates have a distribution that is roughly normal. The mean of the pulse rates is 71.871.8 beats per minute. (Round to one decimal place as needed.) The standard deviation of the pulse rates is 12.212.2...
Trying to verify my answers and R code. Please help!!! The State of Florida has decided to use a factorial design to compare five high schools offering Inter- national Baccalaureate programs with regard to how well the students are doing on a standardized test. Four courses are examined, each with three years of data. The data is as follows, Courses High School IV 48, 44, 46 62, 66, 64 54, 46, 50 57, 53, 55 53, 47, 50 70, 66,...
The following experimental data represent a distribution of driving speeds (in miles per hour) at which individuals were travelling on a highway: 64 68 79 80 64 70 76 67 72 65 73 65 67 65 70 62 67 68 65 64 7) Calculate the 25th, 50th, and 75th percentiles for the data. Based on this, calculate the "interquartile range" (i.e., IQR) for these results 8) Construct a boxplot (box-and-whisker plot) for the data using the technique I described in...
An experiment is conducted to determine if classes offered in an online format are as effective as classes offered in a traditional classroom setting. Students were randomly assigned to one of the two teaching methods. Data below. a. Test the claim that the standard deviations for the two groups are equal. What is the p-value of the test? b. Construct a 95% confidence interval on the difference in expected final exam scores between the two groups. Does the data support...

The accompanying data are the number of wins and the earned run averages (mean number of earned runs allowed per nine innings pitched) for eight baseball pitchers in a recent season. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. If the x-value is not meaningful to predict the value...
6. A bank with a branch located in Crown Point wants to develop an improved process for serving customers during the noon-to-lpm lunch period. Management decides to first study the waiting time of the current process. Data is collected from a random sample of 15 customer and their waiting time is recorded (in minutes) and is located in the Excel data file for this assignment under the tab CPBank. For comparative purposes, similar data is collected from a bank in...
