Major League Baseball requires that its baseballs weigh at least 142 grams and no more than 149 grams.  The weights of baseballs manufactured by a particular company are normally distributed with mean 145.2 grams and standard deviation 1.4 grams.  What proportion of baseballs made by this company meet the major league standard for weight?  (Round your answer to 3 decimal places.)

The four levels of measurement scale are Nominal, Ordinal, Interval and Ratio. What can be computed with each type (Frequency, Median, Mean, Standard Deviation, Standard error, Ratio, Coefficient of variation)?

Answer all questions: 1. What is the range and standard deviation for the following population of scores? Scores: 5,2,5,4

In the 1992 presidential election, Alaska's 40 election districts averaged 2038 votes per district for President Clinton. The standard deviation was 576. (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.a. What is the distribution of X? X ~ N(,)b. Is 2038 a population mean or a sample mean? Select an answer Population Mean Sample Mean c. Find the probability that a randomly selected district had fewer than 1842 votes for President Clinton. d. Find the probability that a randomly selected district had between 1997 and 2099 votes for President Clinton. e. Find the first quartile for votes for President Clinton. Round your answer to the nearest whole number.
