The American Medical Association (AMA) reported a survey of randomly selected adult Americans found that 373 out of 900 men and 275 out of 600 women had been to the hospital in the past 3 years. a) Find the difference in the proportion of women versus men who had been in the hospital in the past 3 years. Show your work. The difference would be 79/1800. b) Find the standard error of the difference in the proportion of women versus men who had been in the hospital in the past 3 years. Show your work. c) Use “PANIC” to find the 95% confidence interval for the difference in the proportion of women versus men who had been in the hospital in the past 3 years.

The blue catfish (Ictalurus Furcatus) is the largest species of North American catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to American Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for 50 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n=50 ;  ¯x=40.49 pounds;  s=3.49 pounds a) Identify the null and alternative hypotheses? H0: H1: b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed c) Identify the appropriate significance…

A sample of 150 married women determined that 127 are happy in their marriage. A sample of 150 married men determined that 76% are happy in their marriage.   If you plan to test if the percent of married women who are happy in their marriage is greater then the percent of married men who are happy in their marriage- Answer the following: What is the test statistic? Write to 4 decimal places.

In a 430-page manuscript, there are 270 randomly distributed misprints. Use the Poison approximation. Find the mean number 2 of misprints per page. Round to one decimal place as needed.

A driver has pumped 13 gallons of gas to his track. On average day that driver has to spend 2 gallons of gas with the deviation 1 gallons. Calculate the probability that these 13 gallons of gas will be enough for next 6 days of driving that track.
