Rock Solid Gym offers several levels of membership status. All customers start at the bronze status. One day, the membership coordinator took a sample ofmembers of the gym. She found that 16 of the 35 members she sampled had bronze status. The gym had 770 members on that day, and 390 of these membershad bronze status.For the membership coordinator's sample, find and write with proper notation the sample proportion and population proportion of members who had bronzestatus. Write the proportions as decimals (not percentages) rounded to two decimal places.(a)Sample proportion: (Choose one) ▼(b) Population proportion: (Choose one)

Given that Sample size (n) = 35 members People with bronze status in sample = 16 Total number of…

The FBI wants to determine the effectiveness of their 10 Most Wanted list. To do so, they need to find out the fraction of people who appear on the list that are actually caught. Step 1 of 2 : Suppose a sample of 716 suspected criminals is drawn. Of these people, 279 were captured. Using the data, estimate the proportion of people who were caught after being on the 10 Most Wanted list. Enter your answer as a fraction or a decimal number rounded to three decimal places.
The FBI wants to determine the effectiveness of their 10 Most Wanted list. To do so, they need to find out the fraction of people who appear on the list that are actually caught. Step 1 of 2: Suppose a sample of 233 suspected criminals is drawn. Of these people, 72 were captured. Using the data, estimate the proportion of people who were caught after being on the 10 Most Wanted list. Enter your answer as a fraction or a decimal number rounded to three decimal places. Step 2 of 2: Suppose a sample of 233 suspected criminals is drawn. Of these people, 72 were captured.

In 2016 the Better Business Bureau settled 84% of complaints they received in the United States. Suppose you have been hired by the Better Business Bureau to investigate the complaints they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate the proportion of complaints the Better Business Bureau is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.84, the same as the overall proportion of complaints settled in 2016. Use the z-table. a. Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of p. E(p) (to 2 decimals) (to 4 decimals) b. Based upon a sample of 200 complaints, what is the probability that the sample proportion will be within 0.04 of the population proportion (to 4 decimals)? probability : = c. Suppose you select a sample of 460 complaints involving new car dealers. Show the sampling distribution of p. E(F) (to 2…
