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 70 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 59 of the 120 college interns had unpaid internships and repeat (a). Are the conclusions the same?....a. Let r be the population proportion. Determine the null hypothesis, Ho, and the alternative hypothesis, H1.Ho: T(Type integers or decimals. Do not round.) If, in a random sample of 100 items, 25 are defective, what is the sample proportion of defective items?p =(Type an integer or a decimal.)

According to the National Highway and Traffic Safety Administration, the proportion of fatal traffic accidents in the United States in which the driver had a positive blood alcohol concentration (BAC) is .36. Suppose a random sample of 105 traffic fatalities in the state of Hawaii results in 51 that involved a positive BAC. D) Check whether the conditions for hypothesis testing using the P-value approach are meet.
According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumer complaints ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a lower proportion of identity theft than 23%? Test at the 5% level. viii) Comparing p-value and α value, which is the correct decision to make for this hypothesis test? A. Reject H B. Fail to reject Ho C. Accept Ho D. Accept HA Enter letter corresponding to correct answer. (ix) Select the statement that most correctly interprets the result of this test: A. The result is statistically significant at .05 level of significance. Evidence supports the claim that the proportion of complaints due to identity theft in Alaska is less than 23%. B. The result is statistically significant at .05 level of significance. There is not…
According to a recent report, 46% of college student internships are unpaid. A recent survey of 60 college interns at a local university found that 30 had unpaid internships. a. Use the five-step p-value approach to hypothesis testing and a 0.10 level of significance to determine whether the proportion of college interns that had unpaid internships is different from 0.46. b. Assume that the study found that 38 of the 60 college interns had unpaid internships and repeat (a). Are the conclusions the same? Question content area bottom Part 1 a.

A Gallup poll taken in May 2000 asked the question, “Which of the following do you think is the primary cause of gun violence in America the availability of guns, the way parents raise their children, or the influences of popular culture such as movies, television, and the Internet?" Fifty-one percent of the n = 493 men and 38% of the n = 538 women sampled responded, “Way parents raise kids." Carry out all the steps of the appropriate hypothesis test to determine if there is sufficient evidence to conclude that a higher proportion of men than women in the population at that time thought “way parents raise kids" is the primary cause of gun violence in America.
