Clark College states that 23% of the student body have dependent children. In a recent survey of stats classes, 70 of the 274 students reported having dependent children. Based on this sample, is there evidence to support the claim that stats classes have a higher percentage of students with dependent children than the college in general?
(a) State the null and alternate hypothesis (symbolic or sentence form).
b) State the p-value (rounded to 3 decimal places)
(c) Draw a conclusion about the claim using a 10% level of significance.

According to a recent report, 45% of college student internships are unpaid. A recent survey of 120 college interns at a local university found that 73 had unpaid internships. a. Use the five-step p-value approach to hypothesis testing and a 0.01 level of significance to determine whether the proportion of college interns that had unpaid internships is different from 0.45. b. Assume that the study found that 66 of the 120 college interns had unpaid internships and repeat (a). Are...

It is stated that the average costof books and supplies for a college student is $402 with a population standard deviation of $138. You would like to test this claim at the level of significance of .05. Using a simple random sample of 50 college students an average of $451 was computed. State the null hypothesis State the alternative hypothesis Calculate the test statistic Calculate the p-value What conclusion will you draw? Repeat the hypothesis test using the critical value approach? What...
A recent article reported that a job awaits only one in three (0.33) new college graduates. The major reasons given were an overabundance of college graduates and a weak economy. A survey of 200 recent graduates from your school revealed that 80 students had jobs. At the .01 significance level, can we conclude that a larger proportion of students at your school have jobs? A The Null Hypothesis is: a Job awaiting new college graduates is _______. b Job awaiting...

Of those students, 195 indicated they planned to perform community service. The following is the setup m the following hypothesis test: H0:p=0.35 Ha:p>0.35 In this example, the p-value was determined to be 0.030. Come to a conclusion...
The average student-loan debt is reported to be $25,235. A student believes that the student-loan debt is higher in her area. She takes a random sample of 100 college students in her area and determines the mean student-loan debt is $27,524 and the standard deviation is $6,000. Is there sufficient evidence to support the student's claim at a 5% significance level? Preliminary: Is it safe to assume that n≤5% of all college students in the local area? Yes No Is...
