please use the calculator method ti 83 or 84 Several insurance adjusters were concerned about the unusually high estimates from Fosbert's U-Bet Repair Station. They obtained the following data: Car Number 1 2 3 4 5 6 7 8 Fosbert's Estimate 2.1 4.5 6.3 3.0 1.2 5.4 7.3 9.3 Nickles' Estimate 2.0 3.8 5.9 2.8 1.3 5.0 6.5 8.6 Estimates are in hundreds of dollars. At a .005 level of significance determine whether the adjusters can conclude that Fosbert's is significantly higher than Nickles'. State hypotheses, P-value, and conclusion.

A researcher interested in determining if there is an association between head circumference and brain volume tested for linear correlation at the a= 0.05 significance level. She took a random sample of twenty adults and measured the head circumference and brain volume (using ultrasound) for each person in the sample. The table above gives the paired data for the twenty adults. The researcher determined there is positive linear correlation between head circumference and brain volume at the 0.05 level of significance. With that information answer the following questions. 1.) Since we've determined there is linear correlation between head circumference and brain volume from the output on the TI83/84 what is "a" the y-intercept of the regression line? A. a=.508 B. a=34.740 C. a=-110.572 D. a=-823.829 2. Since we've determined there is linear correlation between head circumference and brain volume from the output on the T183/84 what is "b" the slope of the regression? A. b=34.740 B. b=.508…
