Seattle, Washington, averages 34 inches of annual precipitation. Assuming that the distribution of precipitation amounts is approximately normal with a standard deviation of 6.5 inches, determine whether an annual precipitation of 28 inches represents a fairly typical year, an extremely wet year, or an extremely dry year.

Assume that the readings on the thermometers are normally distributed with a mean of 0° and standard deviation of 1.00°C. Assume 2.7% of the thermometers are rejected because they have readings that are too high and another 2.7% are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others. Click to view page 1 of the table. Click to view page 2 of the table. Which graph represents the region in which thermometers are rejected? Choose the correct graph below. В. D. The cutoff values are degrees. (Use a comma to separate answers as needed. Round to two decimal places as needed.)

An economist claims that the population standard deviation of the monthly income of all the families that belong to the poverty level is Php 2, 500.00. A group of researchers surveyed 250 families that belong to the poverty level and obtained a mean monthly income of Php 3, 500.00. Assume that the monthly income of the families is approximately normally distributed. What is the population interest? O a. Number of families O b. Poverty level O c. Group of researchers O d. Monthly income

Seattle, Washington averages mean = 34 inches of annual precipitation. Assuming that the distribution of precipitation amounts is approximately normal with a standard deviation of s = 6.5 inches, determine whether each of the following represents a fairly typical year, an extremely wet year, or an extremely dry year. a.  Annual precipitaiton of 41.8 inches b.  Annual precipitaiton of 49.6 inches c.  Annual precipitaiton of 28.0 inches

To assess the air quality in a surgical suite, the presence of colony-forming spores per cubic meter of air is measured on three successive days. The results are as follows: {12, 24, 30}. Calculate the mean and standard deviation for these data.

Find the standard deviation of the following values: 2.58x10-5, 2.33x10-5, 3.28x10-5, 3.57x10-5
