Suppose the average body temperature for apopulation of chimpanzees is 98 degrees F with astandard deviation of 0.5 degrees F. You think that anoutbreak of E. ocrap is underway and you would like toquarantine any individuals that appear to be in the earlystages of infection (individuals in the later stages willsimply die). The first clinical sign of an infection is anirregular body temperature. Here, this is defined as anybody temperature in the 5% extremes of the distributionof temperatures. Use this information to answerquestions 1-3. Question 1. What is the 95%Confidence Interval that would include an acceptablerange of temperatures?

To calculate the 95% Confidence Interval (CI) for the average body temperature of the chimpanzee…

Answered: Suppose the average body temperature…

Entry to a certain University is determined by a national test. The scores on this test are normally distributed with a mean of 500 and a standard deviation of 100. Tom wants to be admitted to this university and he knows that he must score better than at least 80% of the students who took the test. Tom takes the test and scores 595. Will he be admitted to this university?
In a large section of a statistics class, the points for the final exam are normally distributed, with a mean of 74 and a standard deviation of 8. Grades are assigned such that the top 10% receive A's, the next 20% received B's, the middle 40% receive C's, the next 20% receive D's, and the bottom 10% receive F's. Find the lowest score on the final exam that would qualify a student for an A, a B, a C, and a D. Click here to view Page 1 of the Standard Normal Table. Click here to view Page 2 of the Standard Normal Table. The lowest score that would qualify a student for an A is (Round up to the nearest integer as needed.)
Suppose that, for a certain mathematics class, the scores are normally distributed with a mean of 75 and a standard deviation of 9. The teacher wishes to give A's to the top 5% of the students and F's to the bottom 5%. The next 15% in either direction will be given B's and D's, with the other students receiving C's. Find the bottom cutoff for receiving an A grade. (You may need to use the standard normal distribution table. Round your answer to the nearest whole number.)

A particular fruit's weights are normally distributed, with a mean of 613 grams and a standard deviation of 19 grams.If you pick 20 fruits at random, then 11% of the time, their mean weight will be greater than how many grams?Give your answer to the nearest gram.
A population has a mean of u=50 and a standard deviation of 0=10. If 3 points were added to every score in the population, what would be the new values for the mean and standard deviation?
The board of examiners that administers the real estate broker’s examination in a certain state found that the mean score on the test was 450 and the standard deviation was 50. If the board wants to set the passing scores so that only the top 5% of all applicants pass, what should the passing score be? Assume that the scores are normally distributed.
In a large section of a statistics class, the points for the final exam are normally distributed, with a mean of 73 and a standard deviation of 8.

Caleb earned a score of 38 on Exam A that had a mean of 76 and a standard deviation of 20. He is about to take Exam B that has a mean of 150 and a standard deviation of 40. How well must Caleb score on Exam B in order to do equivalently well as he did on Exam A? Assume that scores on each exam are normally distributed.
