3. NASA has been working with utility companies to set up power generating windmills. In order for a site to be effective, the true average wind speed must be more than 20 mph. At a specific site, a sample of thirty-five wind speed readings is taken and the sample average wind speed is 21.4 mph with a standard deviation of 5.4 mph. NASA will only build the windmill if they are sure the true average wind speed is greater than 20 mph. **Should they build the windmill?** Justify by conducting a hypothesis test at α = 0.05. Report the p-value. Describe in the words of the problem what a Type I and a Type II error are and what the consequences of making these errors would be. Make sure to answer the question.

Given The data is as follows: Population mean, μ=20 Sample mean, x¯=21.4 Sample size, n=35 Sample…

Assume that human body temperatures are normally distributed with a mean of 98.20 degrees Fahrenheit with a standard deviation of 0.62. Bellevue Hospital in New York City uses 100.6 degrees as the lowest temperature considered to be a fever. What percentage of normal, healthy persons would be considered to have a fever? Do you think that this cutoff is appropriate? a) b) Physicians want to select a minimum temperature for requiring further medical tests. What should that temperature be if we want only 5.0% of healthy people to exceed it?
A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 2.5 in. A branch of the military requires women's heights to be between 58 in and 80 in. a. Find the percentage of women meeting the height requirement. Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? b. If this branch of the military changes the height requirements so that all women are eligible except the shortest 1% and the tallest 2%, what are the new height requirements?

Assume that human body temperatures are normally distributed with a mean of 98.23°F and standard deviation of .64°F. The hospital uses 100.6°F as the lowest temperature considered to be a fever. What percentage of normal and healthy person's would be considered to have a fever? Does this percentage suggest that a cut off of 100.6°F is appropriate? Physicians want to select a minimum temperature for requiring further medical test. What should the temperature be if we want only 5% of healthy people to exceed it?

A Physics test has a mean of 150 and a standard deviation of 12. A Geography test has a mean of 46 and a standard deviation of 3.5. If both exams are unimodal and symmetric, which is more unusual: A Physics test of 183 or a Geography test of 36?
Most people think that the "normal" adult body temperature is 98.6°F. In a more recent study, researchers reported that a more accurate figure may be 98.1°F. Furthermore, the standard deviation appeared to be around 0.7°F. Assume that a Normal model is appropriate. b) What fraction of people would be expected to have body temperatures above 98.6°F?

A real estate company, We Rent Houses, regularly conducts survey for average rents in Tampa Bay Area. According to its latest survey, the sample mean rent in 2019 was $950 for Pasco County and $1160 in Hillsborough County. Assume the survey sampled rents for 160 rental units in each County. Also, assume the standard deviation in rents based on the survey was $175 in Pasco County and $230 in Hillsborough County. Compute the valued mannually. a. Calculate a 95% confidence interval for the population mean rent for Hillsborough County. Provide an interpretation of the confidence interval. b. Calculate a 95% confidence interval for the population mean for Pasco County. Interpret. c. Is it possible that the population mean rent in Pasco County is higher than that in Hillsborough County? Explain.
4. The specification of the melting point of an alloy is 1200 degrees Celsius. If the melting point differs from this by more than 20 degrees, the composition of the alloy will have to be changed. Assume the melting point is normally distributed with standard deviation 35 degrees. A sample of 25 alloys were obtained and the average melting point were 1224 degrees. By using a = 0.01, determine whether the composition of the alloy will have to be changed? UTM UTM
It is generally believed that the heights of adult females in the U.S. are approximately normally distributed with mean 65 inches and standard deviation 4 inches. A small university is considering custom ordering beds for their dorm rooms. Answer the following questions about the lengths of beds in dorm rooms at this university. A. The beds that the university currently purchases are 70 inches long. What proportion of females will be able to fit on the bed while lying perfectly straight (less than 70”)? Draw/Label/Shade a curve with this information and provide the value of the requested proportion. B. What is the height of a female who is in the top 10% for her height? Draw/Label/Shade
