Use the given data to find the best predicted value of the response variable. Use a significance level of 0.05. Eight pairs of data yield r = 0.472 and the regression equation y= 55.8+2.7x. Also, v=71.13. What is the best predicted value of y for x = 10? O a. 57.80 O b. 449.19 O c. 78.12 O d. 71.13Use the given degree of confidence and sample data to construct a confidence interval for the population mean J. Assume that the population has a normal distribution. The amounts (in ounces) of juice in eight randomly selected juice bottles are: 15.4 15.8 15.4 15.1 15.8 15.9 15.8 15.7 Construct a 98% confidence interval for the mean amount of juice in all such bottles. O a. 15.89 oz
