Because of different sales ability, experience, and devotion, the incomes of real estate agents vary considerably. Suppose that in a large city the annual income is normally distributed with a standard deviation of $15,000. A real estate industry expert claims that the mean annual income of all real estate agent in the city is equal to $79000. A sample of 30 real estate showed that their mean annual income was $84230. Test the manager's claim using a level of significance of 0.05. what is your conclusion
According to the American Automobile Association (AAA), the average cost of a gallon of regular unleaded fuel at gas stations in April 2007 was $2.83 (AAA Fuel Gauge Report). Assume that the standard deviation of such costs is $0.15. Suppose that a random sample of n = 100 gas stations is selected from the population and the April 2007 cost per gallon of regular unleaded fuel is determined for each. Consider , the sample mean cost per gallon. What is the approximate probability that the sample has a mean fuel cost of between $2.57 and $2.90? Please show step by step with formula.
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.

The mean value of land and building per acre from a sample of farms is $1400 with a standard deviation of $300. The data set has a bell shaped distribution. Assume the number of farms in the sample is 71. A) Use the empirical rule to estimate the number of farms whose land and building values per acre are between $800 snd $2000. B) If 25 additional farms were sampled , about how many of these additional farms would you expect to have a land and building values between $800 and $2000?
