The table lists the number of home runs hit and the number of wins of ten randomly selected Major League Baseball teams in the 2019 season. Home Runs   224   279   182   306   249   257   307   167   210   256 Wins   71   106   72   103   97   97   101   77   91   84 a.)  Use StatCrunch to find the scatterplot corresponds to the given data.  (Type the letter of the appropriate scatterplot into the answer box).               [scatterplot] b.) Based on the scatterplot graph, does the data represent a positive, negative or no linear correlation?  (Type either positive, negative, or no linear correlation into the answer box).              [correlation] c.)  Use StatCrunch to find the correlation coefficient r.            r = [r]   (Round to 2 decimals) d.)  Use StatCrunch to find the equation of the linear regression line.  Round each coefficient to 2 decimals.        

A random sample of 30 students was collected to find the heart rate of students. The results were: 52,  57,  64,  64,  65,  65,  66,  68,  68,  68,  68,  69,  70,  71,  71,  73,  73,  73,  74,  75,  78 78,  79,  79,  81,  82,  83,  84,  87,  89 a.)  You will make a frequency table with 6 classes.  Use the Honorlock calculator to find the class width.           [cw] b.)  Form a frequency table with 6 classes.     Class Limits    Frequency    [LL1] – [UL1]    [F1]    [LL2] – [UL2]    [F2]    [LL3] – [UL3]    [F3]    [LL4] – [UL4]    [F4]    [LL5] – [UL5]    [F5]    [LL6] – [UL6]    [F6] c.)  What is the distribution shape:  skewed left, skewed right, bell shaped, or uniform?          [shape]

Scores on the Critical Reading part of SAT exam in recent year were roughly normal with mean of 495 and standard deviation of 118. Use StatCrunch to find the probability that the average score for 30 students exceeds 475.
