The site traffic for a business's website was monitored for 10 days, showing daily traffic of 14,905; 14,910; 14,472; 15,421; 15,114; 14,939; 14,891; 15,803; 16,442; 14,681. Calculate the standard deviation of the dataset. 1) 554.86 2) 14,924.5 3) 151,578 4) 584.87 5) 15,157.8

Given the data points, 8.12 8.08.8.05-8.16 8.11.8.17,8.14, calculate the Standard Error in the Mean. Select one: O a. 0.00196 Оь. 0.01289 O c. 0.04298 O d. 0.01625 Oa.

Fifteen randomly selected college students were asked to state the number of hours they slept the night before. The resulting data are: 6 16 7 8 7 796 3 11 9 15 4 7 9 a) Find the mean. b) Find the median. c) Find the standard deviation. d) According to Chebysev's Theorem, at least 75% of the times will fall between what two amounts? Is the theorem accurate for this set of data? Why of Why not? e) Are any of the reported hours "unusually" high? Are any of the reported hours unusually low?

A boat capsized and sank in a lake. Based on an assumption of a mean weight of 133 Ib, the boat was rated to carry 70 passengers (so the load limit was 9,310 Ib). After the boat sank, the assumed mean weight for similar boats was changed from 133 lb to 174 lb. Complete parts a and b below. a. Assume that a similar boat is loaded with 70 passengers, and assume that the weights of people are normally distributed with mean of 181.1 Ib and a standard deviation of 38.6 lb. Find the probability that the boat is overloaded because the 70 passengers have mean weight greater than 133 lb The probability isO: (Round to four decimal places as needed.) b. The boat was later rated to carry only 17 passengers, and the load limit was changed to 2,958 Ib. Find the probability that the boat is overloaded because the mean weight of the passengers is greater than 174 (so that their total weight is greater than the maximum capacity of 2,958 Ib). The probability is. (Round to four decimal places as needed.)…
