A survey of hospital records of 35 randomly selected patients suffering from a particular disease indicated that the average hospital stay was 10 days. If the mean hospital stay is between 9.032 and 10.97 days with a standard deviation of 2.9 days, approximately which confidence level does the range represent? Estimate the z-score to the nearest thousandth and use it to determine the confidence level.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
