The U.S. Department of Transportation estimates that 10% of Americans carpool. Does that imply that 10% of cars will have two or moreoccupants? A sample of 300 cars traveling southbound on the New Jersey Turnpike yesterday revealed that 63 had two or moreoccupants. At the 0.01 significance level, can we conclude that 10% of cars traveling on the New Jersey Turnpike have two or moreoccupants?a. State the null hypothesis and the alternate hypothesis.

A researcher has observed 500 vehicles at a stop sign in a suburban neighbourhood and recorded the type of vehicle (sedan, hatchback, bakkie) and driver behaviour at the stop sign (complete stop, near stop, “ran” the stop sign). At the 0.05 level of significance, could there be some relationship between driver behaviour and the type of vehicle being driven? Define the null hypothesis and the alternative hypothesis. A. H1: Driver’s behaviour and type of vehicle are independent vs H0: A relationship exists between driver’s behaviour and type of vehicle B. H0: A relationship exists between driver’s behaviour and type of vehicle vs H1: No relationship exists between driver’s behaviour and type of vehicle C. H0: Driver’s behaviour and dependent on the type of vehicle vs H1: Driver’s behaviour and type of vehicle are independent D. H0: Driver’s behaviour and type of vehicle are independent vs H1: A relationship exists between driver’s behaviour and type of vehicle
A clinical trial tests a method designed to increase the probability of conceiving a girl. In the study, 362 babies were born, and 211 of them were girls. Use the sample data with the 0.01 significance level to test the claim that with this method, the probability of having a baby being a girl is greater than 0.5. Use this information to answer the following questions.

K In a July 2017 report, a research firm stated that 39% of people from a certain region reported being harassed while online. An AP Statistics student decided to conduct her own survey at her high school of 3,260 students. She randomly selected 239 students to be surveyed and 99 of them stated that they had been harassed online. Does her survey suggest that the problem is worse at her school than it is for a typical person in the region? Determine the appropriate hypotheses. Ho P HA P (Type integers or decimals.) The test statistic is z = (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) State your conclusion. Use a = 0.05. the null hypothesis. There sufficient evidence to conclude that the proportion of students in the high school who were harassed while online is the proportion of people from the region being harassed while online.
Suppose that in a random selection of 100 colored candies, 22% of them are blue. The candy company claims that the percentage of blue candies is equal to 28%.

A study conducted among college students looked at the influence of religiosity (high, medium, or low) on anger frequency (never, sometimes, or often) in the last month. The responses of randomly selected college students at a large school in the United States are shown in the following table. Anger Frequency Never Sometimes Often High 214 What is the correct conclusion for this hypothesis test? 145 29 Medium 129 61 18 Low 60 55 27 You want to determine if anger frequency and religiosity are independent. Use a level of significance of a = 0.10. O As the P-value is less than a, we reject the null hypothesis. Thus, there is sufficient evidence to conclude that anger frequency and religiosity are not independent. O As the P-value is less than a, we reject the null hypothesis. Thus, there is insufficient evidence to conclude that anger frequency and religiosity are not independent. O As the P-value is less than a, we fail to reject the null hypothesis. Thus, there is sufficient evidence to…
You want to see if it your cholce of lane makes a difference in how many cars you have to deal with. You randomly observe 267 cars as they pass by on the three lane freeway. The results are displayed in the table below. a. What are the null and alternative hypotheses? Ho: Select an answer H: Select an answer b. Complete the rest of the table by filling in the expected frequencies: Outcome Frequency Expected Frequency Lane 1 82 Lane 2 95 Lane 3 90 Frequency of Cars in Each Lane c. Do a hypothesis test with a = 0.05. Give either the test statistic, X, or the p-value (Identify which one you're giving). Then, give your conclusion based on the original question.
