We want to analyze the number of reported cases of the disease COVID-19 per day in Minneapolis. A random sample of 45 days in 2020 revealed the average number of cases to be 116 with a standard deviation of 50. We want to calculate a 95% confidence interval. Round your answer for part (a) to the nearest whole number. (a) What is the point estimate for the population mean number of cases in Minneapolis per day? Round your answer for part (b) to 2 decimal places. (b) What is the critical value z that will need to be used to calculate a 95% confidence interval? Round your final answers for part (c) to one decimal place accuracy. (c) What is the 95% confidence interval for the number of COVID-19 cases per day in Minneapolis? Answer: We can be 95% confident that the true population mean number of COVID-19 cases per day in Minneapolis lies in the interval Round your answer for part (d) UP to the nearest whole number. (d) Determine the minimum sample size (number of days) required if the precision of the estimation is to be within 1 9 (with a 95% confidence level and the standard deviation remains the same). Cub
