The Gaming Control Board conducts an investigation into the Blackjack table at a casino by tracking the proportiod of cards played in a full day that have value 10. Let p be the proportion of care alue 10. If the casino is using a fair deck, this should be 30.79% of the cards. Based on each confidence interval for p. make a formal statistical decision for the hypotheses below. Check your answers carefully. No partial credit on this one!

You want to conduct a study to estimate the percentage of robberies in Texas that result in arrests. Your goal is to have Margin of Error of 0.04 and a Confidence Level of 80%. n is =?
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
Cody took his first physics exam and scored an 80. The population mean for this exam is 70, and the standard deviation is 5. What is the probability of selecting a person with a score greater than Cody’s?
You are planning on applying to the Knirhsdaeh institute as a psychology counselor. They hire millions of psychologists around the world. You know the standard deviation for the salaries is $13 k. To find the average, you sample 18 random employees and get an average salary of $65 k. Find an 92% confidence interval for the true average salary of Knirhsdaeh employees.Use 2 decimal places
Salaries of 25 college graduates who took a statistics course in college have a mean of $79,350 and a standard deviation of $1,280. Construct a 98% confidence interval for estimating the population standard deviation. Enter the upper bound of the confidence interval. (Round your answer to nearest whole dollar.)
According to a report on consumer fraud and identity theft, 20% of all complaints for a year were for identity theft. In that year, California had 724 complaints of identity theft out of 3466 consumer complaints. Does this data provide enough evidence to show that California had a higher proportion of identity theft than 20%? Test at the 5% level. State the hypotheses. Ho: P ? ✓ Ha: P?V Calculate the test statistic. Round to four decimal places. Ô = Calculate the standardized test statistic. Round to three decimal places. Z= Find the p-value. Round to four decimal places. p-value = State your decision. O Since the p-value is less than .05, reject Ho. O Since the p-value is less than .05, fail to reject Ho. Since the p-value is greater than .05, fail to reject Ho. Since the p-value is greater than .05, reject Ho. Interpret the results. O At the 5% level of significance, there is not enough evidence to show that the proportion of complaints due to identity theft in California is not…
10. Several years ago, 51% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,075 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,075 surveyed, 472 indicated that they were satisfied. Construct a 99% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. What are the null and alternative hypotheses? Ho: p (1) versus H1: p (2) (Round to two decimal places as needed.) Use technology to find the 99% confidence interval. The lower bound is The upper bound is (Round to two decimal places as needed.) What is the correct conclusion? O A. Since the interval contains the proportion stated in the null hypothesis, there is insufficient evidence that parents' att O B. Since the interval contains the proportion stated in the null hypothesis, there is sufficient…
n a survey, 23 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $31 and standard deviation of $17. Construct a confidence interval at a 95% confidence level.Give your answers to one decimal place. +-Interpret your confidence interval in the context of this problem.
