The doctor plans to run a left-tailed t - test for no linear relationship, set at a significance level of α = 0.05 . the standard error of the slope, se b 1 , is 0.81814. she performs model diagnostics and observes that the normal probability plot is linear and the residual plot has a random pattern.
compute the t - statistic for the test. provide your answer with precision to three decimal places. avoid rounding until the final step. compute the degrees of freedom for the t - statistic. select the appropriate null hypothesis statement, h 0 , and alternative hypothesis statement, h 1 , for the doctor's hypothesis test for no linear relationship.

Someone answer asap for ! max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a. the median of max’s data is 250 b. more than half of the data points max recorded were 177 centimeters. c. a data point chosen at random is as likely to be above the mean as it is to be below the mean. d. every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
