Q: a.Twelve homes in one city were underinsured on the average of $5,000, 24 homes in another city were underinsured on the average of $6,200 and 14 homes in a third city were underinsured on the average of $6,900. Find the overall average amount of the underinsured homes. b. A writer earns a mean average of $15.00 per hour for 4 hours of work, $17.50 per hour for 2 hours of work, $13.33 per hour for 3 hours and $14.00 per hour for 1 hour. What is the overall average earning per hour of the writer?
Previously, an organization reported that teenagers spend 8.5 hours per week, on average, on the phone. The organization thinks that, currently, the mean is higher. Twenty-three randomly chosen teenagers were asked how many hours per week they spend on the phone, with the following results (in hours): 8.3, 8.5, 10.5, 2.9, 6.7, 7.7, 13.8, 7.8, 8.7, 11.8, 12, 6.1, 5.4, 5.8, 8.5, 7.9, 10.1,11.1, 11.6, 12.9, 3.6, 6.4, 11.2 Perform a hypothesis test using a 3% level of significance. Step 1: State the null and alternative hypotheses. Ho: ??v H: ? v ? v (So we will be performing a Select an answer v test.) Step 2: Assuming the null hypothesis is true, determine the features of the distribution of point estimates using the Central Limit Theorem. v with By the Central Limit Theorem, we know that the point estimates are Select an answer and distribution standard deviation distribution mean Step 3: Find the p-value of the point estimate. P? v? v = P(| ? ♥| ? v

A De Anza student decided to determine whether the percent of men who participate in sports at De Anza College is higher than the percent of women who participate in sports at De Anza College. Out of 67 women, 12 said they participate in sports. 13 of the 45 men surveyed said they participate in sports. a. ) What are the type I and type II errors? Explain them in the context of this problem.b. ) Describe the sample statistics in words. What is the distribution of the sample statistic? Explain why you used this distribution.Can someone please help me make sense of these questions?
Does the type of instruction in a college statistics class (either lecture or self-paced) influence students’ performance, as measured by the number of quizzes successfully completed during the semester? Twelve students were recruited for the study. Students received the lecture instruction or a self-paced instruction. The total number of quizzes completed during teach type of instruction appear below.
The U.S. National Center for Health Statistics complies birth statistics and publishes the results in vital statistics of the United States. The Center has historically believed that the mean of all newborns in the U.S. has been no less than 6.95 pounds. A sample of babies is selected so that the center can revise its belief. The following birth weights, in pounds are recorded: 7.4, 6.0, 8.6, 4.5, 2.0, 7.9, 4.0, 2.6, 5.9, 7.3, 7.3, 7.0, 6.3, 8.1, 7.1, 7.3, 6.6, 5.2, 9.8, 8.0, 10.9, 6.5, 3.8, 5.0, 8.0 a). At 5% level of significance, do these data provide sufficient evidence to refute the Center’s belief? Your conclusion must be in terms of the P-Value as well as setting up a Rejection Region. You must show all necessary work. b). Which statistical distribution should be applied in this situation and why? Explain carefully.
To decide between using an independent-samples t test and a paired-samples t test, what question should the researcher ask? a. Is the goal to measure association or to make a prediction? b.
