Use StatCrunch to determine the count and percentage of observations falling in each of these intervals by following the instructions listed below or using another appropriate counting method. Properly label and list these counts and percentages in your document.
Start in the “Body Temp” data set. Go to Data Row Selection Interactive Tools. In the slider selectors box, click the variable Body Temp into the variable box. Then Click compute.
I got this answer:
68% of the data falls within one standard deviations
68% confidence interval of mean
=98.25+/-0.733
=(97.52, 98.98)
95% of the data falls within two standard deviations
95% confidence interval of mean
=98.25+/-2*0.733
=(96.78, 99.72)
99.7% of the data falls within three standard deviations
99.7% confidence interval of mean
=98.25+/-3*0.733
=(96.05, 100.45)
The box that appears has a slider under the words Body Temp that allows you to create ranges of temperatures that you determined in 4d. Use the slider to obtain the count by looking at the “# rows selected” presented in the first line of the box. Calculate the percentages from the counts you obtained.
I need the answer to this and the rest please!
