NHL Assists and Total Points A random sample of scoring leaders from the National Hockey League (NHL) showed the following numbers of assists and total points. Based on these data, can it be concluded that there is a significant relationship between the two? Draw the scatter plot for the variables. NHL Assist and Points  Compute the value of the correlation coefficient. Round your answer to at least three decimal places. r=    Assists       59    68    44    58    67    69 Total points       109    101    95    109    91    89 State the Hypothesis. H0:  H1:  Test the significance of the correlation coefficient at =α0.05, using The Critical Values for the PPMC Table. Critical value(s): +or- = Reject or do not reject the null hypothesis.

PLEASE HELP ANSWER ALL SUBS D-i THANK YOU A grocery store manager did a study to look at the relationship between the amount of time (in minutes) customers spend in the store and the amount of money (in dollars) they spend. The results of the survey are shown below. PLAESE ANSWER ALL SUBS A-i its all one question   Time 24 19 21 20 18 24 25     Money 102 78 79 80 72 84 105       A. Find the correlation coefficient: r=     Round to 2 decimal places.  The null and alternative hypotheses for correlation are:H0: ρ  = 0H1: ρ  ≠ 0     B.The p-value is:?        (Round to four decimal places) C. Use a level of significance of α=0.05 to state the conclusion of the hypothesis test in the context of the study? There is statistically insignificant evidence to conclude that a customer who spends more time at the store will spend more money than a customer who spends less time at the store. There is statistically significant evidence to conclude that a customer who spends more time at the…
