Question

A sample of 26women is​ obtained, and their heights​ (in inches) and pulse rates​ (in beats per​ minute) are measured. The linear correlation coefficient is 0.208and the equation of the regression line is ModifyingAbove y with caret equals 17.8 plus 0.940 x​,where x represents height. The mean of the 26heights is 63.5in and the mean of the 26pulse rates is 77.9beats per minute. Find the best predicted pulse rate of a woman who is 71in tall.

    Answer:

    The pulse rate is 84.54bpm

    Step-by-step explanation:

    Given

    \^{} y = 17.8 + 0.940x

    Required

    Find \^{}y when x = 71

    Substitute 71 for x in: \^{} y = 17.8 + 0.940x

    \^{} y = 17.8 + 0.940 * 71

    \^{} y = 17.8 + 66.74

    \^{} y = 84.54

    The pulse rate is 84.54bpm
