Hi tutor, thanks for all you do. Please take your time and verify accuracy of your answers. This is not due for me until tomorrow night.

Solve the problem. 12) Human body temperatures are normally distributed with a mean of 98.20 F and a standard 12) deviation of 0.62"F. If 19 people are randomly selected, find the probability that their mean body temperature will be less than 98.50 F. A) 0.0833 B) 0.3343 C) 0.9826 D) 0.4826 13) The annual precipitation amounts in a certain mountain range are normally distributed with a 13) mean of 95 inches, and a standard deviation of 16 inches. What is the probability that the mean annual precipitation during 64 randomly picked years will be less than 97.8 inches? A) 0.5808 B) 0.9192 C) 0.4192 D) 0.0808 Express the confidence interval using the indicated format. 14) Express the confidence interval (0.571, 0.679) in the form of p + E. 14) A) 0.571 + 0.054 B) 0.571 + 0.108 C) 0.625 + 0.054 D) 0.625 + 0.108 Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. 15) n = 152, x = 125; 95% confidence 15) A) 0.773 27 D) Ho: U = 27 H1: 1 > 27 H1: 1 =27 H1: 1 $ 27 H1:
