The Mayo Clinic recommends that adults sleep 8 hours per night. 79 randomly selected college students were asked how many hours they slept the previous night, and the distribution of their responses was bell shaped with a mean of 7 hours and a standard deviation of 2.1 hours. Use the Empirical Rule to answer the following questions. a) 68% of the students slept between hours and hours per night. b) 95% of the students slept between hours and hours per night. c) 99,7% of the students slent between

Compute mean, median, and mode for patient loads for the seven doctors. b. Compute the range of patients seen per day. c. Compute the standard deviation.
1. The average number of acres burned by forest and range fires in a large New Mexico county is 4,255 acres per year, with a standard deviation of 744 acres. The distribution of the number of acres burned is normal. a.) What is the probability that between 2,540 and 4,190 acres will be burned in any given year? b.)What number of burnt acres corresponds to the 38th percentile?
The mean work week for engineers in start-up companies is claimed to be about 59 hours with a standard deviation of 6 hours. Kara, a newly hired engineer hopes that it's not (she wants it to be shorter). She asks 10 engineers in start-ups for the lengths of their mean work weeks. Their responses are 70; 45; 55; 60; 65; 55; 55; 60; 50; 55.a. Is the newly hired engineer testing a mean or a proportion? mean proportion Correct b. The null hypothesis (or company claim), in symbols, is μ=μ=Correct.c. If the claim is correct, what is the probability that a sample mean would be as low as Kara's mean?Incorrect %Give your answer as a percentage accurate to one decimal place.
