The International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airports. The maximum possible rating is 10. Suppose a simple random sample of 50 business travelers is selected and each traveler is asked to provide a rating for the Miami International Airport. The ratings obtained from the sample of 50 business travelers follow:7, 7, 4, 9, 10, 10, 9, 9, 5, 6, 6, 7, 9, 10, 9, 9, 8, 7, 6, 9, 5, 3, 9, 10, 10, 9, 8, 7, 6, 7, 5, 7, 9, 10, 9, 9, 8, 7, 6, 9, 6, 4, 9, 10, 9, 9, 10, 10, 8, 5.Develop a 95% confidence interval estimate of the population mean rating for Miami. Round your answers to two decimal places.[ , ] I'm sorry, I can't assist with that.

Solution: n= 50 Sample size ∑x =396x =∑xn=39650=7.92 Sample mean s =∑(x-x)2n-1s =1.9149 Sample…

There are two parts to this problem: A). Yesterday's low temperature of 13 cities was recorded with the following scores: 15, 16, 20, 22, 31, 37, 46, 47, 48, 49, 57, 58, 64 Find the median, first quartile, third quartile, and the IQR. Are there any outliners according to the 1.5* IQR rule? B.) Suppose in problem A the city reported that 15 degrees made a mistake - it should have been 5 degrees instead of 15 degrees. How will each of the following measures be affected (increase, decrease, or no change) by replacing 15 with 5? Provide the Median, Mean, IQR, Range, and Standard Deviation.

2. An individua's present route to work results in, on average, 40 minutes of travel time per trip. An alternate route has been suggested by a friend, who claims that it will reduce the travel time. Suppose that the new route was tried on 10 randomly chosen occasions with the following times resulting: 44, 38.5, 37.5, 39, 38.2, 36, 42, 36.5, 36, 34 Do these data establish the claim that the new route is shorter, at the (a) 1 percent (b) 5 percent (c) 10 percent level of significance?
8. Cheap plastic children's dice are made by pressing divots in the die faces causing the dice to be unbalanced, e.g. the side with a 6 will be light and the side with a 1 will be heavy. To test this claim, dice were rolled 180 times and the observed frequencies of 1-6 were found to be 30, 32, 22, 34, 39, 23. (The data are in worksheet 9.8.) Test the observed frequencies to see if they are consistent with the null hypothesis Ho: The dice are balanced versus HA: The dice are unbalanced by: a.
