A machine used to fill gallon-sized paint cans is regulated so that the amount of paint dispensed has a mean of 128 ounces and a standard deviation of 0.40 ounce. You randomly select 45 cans and carefully measure the contents. The sample mean of the cans is 127.9 ounces. Does the machine need to be reset? Explain your reasoning. V, it is that you would have randomly sampled 45 cans with a mean equal to 127.9 ounces, because it within the range of a usual event, namely within of the mean of the sample means.

In the 1992 presidential election, Alaska's 40 election districts averaged 1980 votes per district for President Clinton. The standard deviation was 573. (There are only 40 election districts in Alaska.) The distribution of the votes per district for President Clinton was bell-shaped. Let X = number of votes for President Clinton for an election district. (Source: The World Almanac and Book of Facts) Round all answers except part e. to 4 decimal places.PLEASE ANSWER C, D AND E AND ROUND TO THE 4 DECIMALc. Find the probability that a randomly selected district had fewer than 2062 votes for President Clinton. d. Find the probability that a randomly selected district had between 2052 and 2347 votes for President Clinton. e. Find the first quartile for votes for President Clinton. Round your answer to the nearest whole number.

From the states data set, get the descriptive statistics for the violent crime rate. For this assignment, you will need the mean, standard deviation, five-number summary (minimum, 25th percentile, median, 75th percentile, maximum), and interquartile range. Submit all answers as whole numbers--no decimal points. If you have to calculate the interquartile range by hand, you may calculate it using whole numbers as the 25th and 75 percentile. How would i calculate this?
