3. Based on a random sample of 500 measurements, the sample proport Consider the test of hypothesis: Но: π-0.30 На: п < 0.30 with a-0.05 Calculate the test statistic z, the P-value, and make a decision about Ho. a. b. Construct a 95% confidence interval for the true population proportion Assuming the same confidence level as in the population proportion question (part b above), what sample size would be required to reduce the margin of error of the confidence interval...
1. You own a small storefront retail business and are interested in determining the average amount of money a typical customer spends per visit to your store. You take a random sample over the course of a month for 8 customers and find that the average dollar amount spent per transaction per customer is $106.745 with a standard deviation of $13.7164. Create a 95% confidence interval for the true average spent on all customers per transaction. Question 1 options: 1)...
Can you do both please and help a girl out XOXO :)options are if the p-value is either greater or less than 0.01. Researchers conducted a follow-up study predicting the outcomes of races in the House of Representatives with 189 correct predictions out of 279. Using a simulation and the 25D method, the 95% confidence interval is (0.62, 0.74) and using a theory-based approach, the 95% confidence interval for these data is (0.62,0.73). When comparing the 25D method and theory...
QUESTION 04 (10 points)-Confidence Interval for π in Finite Population Case A cohort of 2,469 veterans has an unknown probability of home ownership t. A simple random sample of 354 is drawn without replacement. The number of home owners in the sample is 148. (a)[2] Check if this is the finite population case. (b)[2] Check if the sampling distribution of the sample proportion can be approximately Normal (c) [3] Construct the 98% CI for the population proportion π. Sketch the...
The owner of a golf course wants to determine if his golf course is more difficult than the one his friend owns. He has 11 golfers play a round of 18 holes on his golf course and records their scores. Later that week, he has the same 11 golfers play a round of golf on his friend's course and records their scores again. The average difference in the scores (treated as the scores on his course - the scores on...
