unknown
) and
assumed unequal
). Sample size (female-24, male-28) Sample mean grade (female-29.8, male-27.3) Sample variance ( female-6,554, male-3,276)
a)
Test whether or not the average grade of females is significantly greater than that of males at
⍺

significance level?
b)
Develop 90 % confidence interval estimate of the difference between grade
of the female and male
students.

Researchers equipped random samples of 46 male and 58 female
students from a large university with a small device that secretly
records sound for a random 30 seconds during each 12.5-minute
period over two days. Then they counted the number of words spoken
by each subject during each recording period and, from this,
estimated how many words per day each subject speaks. The female
estimates had a mean of 16,177 words per day with a standard
deviation of 7520 words...

1. A university has 10,000 students of which 45% are male and
55% are female. If a class of 30 students is chosen at random from
the university population, find the mean and variance of the number
of male students. Group of answer choices Mean = 16.5, Variance =
2.7 Mean = 13.5, Variance = 2.7 Mean = 16.5, Variance = 7.4 Mean =

At a very large university, the mean weight of male students is
197.3 pounds with a standard deviation of 15.2 pounds. Let us
assume that the weight of any student is independent from the
weight of any other student. Suppose, we randomly select 256 male
students from the university and look at the weight of each student
in pounds. Let M be the random variable representing the mean
weight of the selected students in pounds. Let T = the random...
