Schools often report their admissions requirements using middle 50% data. Amos Tuck (DartmouthBusiness School) uses the following formula to calculate a combination of grade point average andGMAT.Admission Score = 200*GPA + GMATGiven that the population of Amos Tuck entering class for the past few year has been averaging thefollowing25th-percentile: 125075th-percentile: 1400Using the above information and the assumption of a normal distribution, what is the probability ofMark, who has a GPA of 3.5 and a GMAT score of 690, being admitted; vs. Anna, who has a GPA of 3.0and a GMAT score of 550, being admitted.

The formula to calculate the admission score is given as: Admission score=200*GPA+GMAT Given that,…

Español A r.able indicator of a baby's health is the weight gained in the fir year of the baby's life. Assume that the population of all such weight gains for baby boys is approximately normally distributed. A study claimed that the mean of this population is 3.454 kg. As a practicing pediatrician, you want to test this claim. So, you select a random sample of baby boys, and you record the weight each gained in their first year. Follow the steps below to construct a 95% confidence interval for the population mean of all the weight gains for baby boys in their first year. Then state whether the confidence interval you construct contradicts the study's claim. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results for your random sample. Take Sample Sample size: 0 Point estimate: 0 Sample standard deviation: 0 Critical value: 0 Enter the values of the sample size, the point estimate of the mean, the sample standard deviation, and the critical value you…
