Several years ago, 45% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1 comma 015 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1 comma 015 surveyed, 464 indicated that they were satisfied. Construct a 90% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. Use technology to find the 90% confidence interval.

You've surveyed the student body about time spent on coursework each week. The mean (??) is 8.3 hours with a standard deviation (??) of .85 hours. What is the probability of a student reporting working 10 hours or more each week on course work? What is the probability of a student reporting 5 hours or less on coursework? What proportion of students report doing coursework between 7 and 9 hours per week? How many hours would a student do coursework if he or she worked longer than 95% of other students?

a) Test whether or not the average grade of females is
significantly greater than that of males at ⍺=0,05 % significance
level?
b) Develop 90 % confidence interval estimate of the difference
between grade of the female and male students.

9)A professor gave a quiz in a statistical methods class and created a histogram to observe the shape of the data. What would be the expected shape of the histogram if
a) the quiz is very easy
b) the quiz is very difficult
c) few students had high scores and few had low scores. Rest of them were in the middle, around (both sides) of the average score.
d) half of the students in the class have had good math background, other half have had no prior college math courses. The quiz emphasizes higher level math skills.

A researcher was interested in whether the female students who enrolled in her stats course were more interested in the topic than the males. The researcher obtained a random sample of 8 male and 8 female students and gathered their scores on an Interest in Statistical Topics (IST) Survey.
Girls’ IST scores: 21, 37, 22, 20, 22, 20, 22, 21
Boys’ IST scores: 20, 20, 20, 21, 21, 20, 23, 21
Test the researcher’s hypothesis using α =.05
Please show answer testing for equal variances.

Consider three students taking an examination. Their respective probabilities of obtaining the different available grades are shown in Table 1. (a) What is the probability that each will obtain a grade of A? (b) If two students were to receive an A, what is the probability that Jim would be among them?
Table 1. Probabilities of Individual Student Exam Grades*
Student Grade
A B C D F
Terry 0.5 0.3 0.1 0.06 0.04
Jim 0.4 0.4 0.1 0.07 0.03
Sam 0.3 0.3 0.3 0.05 0.05
