1. Final: United Motors claims that one of its cars, the Starbird 300, gets city driving mileages that are normally distributed with a mean of 30 mpg and a standard deviation of 1 mpg. Let x denote the city driving mileage of a randomly selected Starbird 30O. Assuming that United Motors' claim is correct, find P(x <= 27). O a. .00263 O b..00365 Oc.00629 O d. .00135 e. None of the above

According to a recent​ publication, the mean price of new mobile homes is $65,100. Assume a standard deviation of $7700. Let x denote the mean price of a sample of new mobile homes.   a. For samples of 50 mobile homes, the mean and standard deviation of all possible sample mean prices are $_________ and ​$__________​, respectively. ​(Round to the nearest cent as​ needed.) b. For samples of 200 mobile homes, the mean and standard deviation of all possible sample mean prices are ​$________and ​$_________​, respectively. ​(Round to the nearest cent as​ needed.)
