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?

Sample Size
Sample Mean Grade Sample Variance
Female Male
24 28 29.8 27.3 6,554 3,276
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.
Not: You have to draw the table to see which area that you have to calculate

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
