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 unpaidinternships.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 unpaidinternships is different from 0.45.b. Assume that the study found that 64 of the 120 college interns had unpaid internships and repeat (a). Are the conclusions the same?a. Let a be the population proportion. Determine the null hypothesis, Ho, and the alternative hypothesis, H,.Ho: T

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…
A health provider saw that 48% of their members received their flu shot in recent years. The health care provider tried a new advertising strategy the following year, and they took a sample of members to test if the proportion who received their flu shot had changed. Determine the null and alternative hypothesis
State the general steps of the P-value approach to hypothesis testing.
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.
In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that σ = 2. Using 40 students as the sample, conduct a hypothesis test to determine if the average for students at your school is lower:
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.

According to Emergency Room Statistics, in any 6 month period, 15.2% of asthmatic children not on inhalers will have an asthmatic complication requiring the emergency room. A pharmaceutical firm has developed a new steroidal inhaler. The company believes that the use of this steroidal inhaler will decrease the percentage of asthmatic children requiring emergency room care for asthmatic complications. Because the FDA requires 2-sided hypothesis tests, the company tested the following claim: In any 6 month period, the percentage of asthmatic children using their steroidal inhaler that require emergency room care for asthmatic complications will not be 15.2%. To test their claim, they took a simple random sample of 260 asthmatic children and had them use a steroidal inhaler for 6 months. Of the 260 children, 60 required emergency room care for asthmatic complications at some time in the 6 month period. (c) What is the critical value which represents a boundary between the rejection region…
Over the past few decades, public health officials have examined the link between weight concerns and teen girls’ smoking. Researchers surveyed a group of 273 randomly selected teen girls living in Massachusetts (between 12 and 15 years old). After four years the girls were surveyed again. Sixty-three said they smoked to stay thin. Is there good evidence that more than thirty percent of the teen girls smoke to stay thin? Solve the following problems using the steps in conducting hypothesis tests.
According to a recent report, 46% of college student internships are unpaid. A recent survey of 80 college interns at a local university found that 51 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 0.46. b. Assume that the study found that 42 of the 80 college interns had unpaid internships and repeat (a). Are the conclusions the same? a. Let π be the population proportion.
