Question

how many rounds of golf do those physicians who play golf play per year? a survey of 12 physicians revealed the following numbers:estimate with 91% confidence the mean number of rounds played per year by physicians, assuming that the population is normally distributed with a standard deviation of 8.note: for each confidence interval, enter your answer in the form (lcl, ucl). you must include the parentheses and the comma between the confidence limits.confidence interval

Answer 1

To estimate the mean number of rounds played per year by physicians, we can use the formula for a confidence interval.

Step-by-step explanation:

To estimate the mean number of rounds played per year by physicians, we can use the formula for a confidence interval:

(mean - z * (standard deviation / sqrt(n)), mean + z * (standard deviation / sqrt(n)))

Given that there are 12 physicians, a confidence level of 91%, a standard deviation of 8, and a normal distribution, the formula becomes:

(mean - 1.695 * (8 / sqrt(12)), mean + 1.695 * (8 / sqrt(12)))

So the estimated mean number of rounds played per year by physicians is (mean - 5.188, mean + 5.188) with 91% confidence.
