The researcher wanted to know whether there is a relationship between the number ofbranches a bank has & the total number of deposits (in billions of dollars) the bankreceives. So, eight regional banks are selected as the sample. Then, the number ofbranches and the number of deposits made are given in the table below. At 0.05 levelof significance, determine if there is a significant correlation between the number ofbranches & the number of deposits made.BankNumber of BranchesDeposits (in billion $)P2092335331197Y20112T34426A132401241264

A pediatrician wants to determine the relation that may exist between a child's height and head circumference. She randomly selects 8 children, measures their height and head circumference, and obtains the data shown in the table. The pediatrician wants to use height to predict head circumference.

Warren wants to know if the amount of coffee that you drink is related to the number of hours that you stay awake. He recruits 50 participants using random sampling to report how much coffee they drank and the time of the day that they went to sleep. He then performs a correlation to determine the association between the amount of coffee that was consumed and the number of hours that they stayed awake. There was a statistically significant positive correlation between amount of coffee that participants drank and the number of hours that they stayed awake, r(49) = .82, p < .05, two-tailed, r2 = .08. This was a small effect – 8% of the variance in the amount of coffee drank is explained by hours that you stay awake (and vice versa).
