The test results of a correlation analysis conducted to assess the relationship between body mass index and body fat percentage indicated a Pearson correlation coefficient (r) value of 0.71. Interpret the r value in terms of strength and direction. The significance (p= 0.14) was tested at α = 0.01. Was there a statistically significant correlation between body mass index and body fat percentage? How did you arrive at your conclusion?

Answer #1

No, there is not significant correlation between body mass index and body fat percwntage.

For this test null hypothesis is r=0 and alternate hypothesis is r 0. Now, P value is 0.14,which is greater than significance level 0.01. So, we fail to reject null hypothesis and conclude there is not enough evident to support the claim r 0. So, there is no significant correlation.

Please support me by giving thumbs up. Thank you.

Investigators studied the relationship between screen time (measured in hours/week) and body- mass-index, BMI= wt/ht2 (wt = weight in kg and ht = height in meters), in men age 25 - 45 . They surveyed 6234 U.S. men in this age group, the scatter diagram for the data was homoscedastic and the BMI data was approximately normally distributed both unconditionally and in each vertical strip. The investigators generated the following summary statistics: X=35 SDX=12 Y = 27 SDY = 6...
