4116 male teenagers were sampled. Their heights and weights were measured. The linear regression results are below. Use these results to estimate the weight (in pounds) of a male teenager who is inches tall. Round your answer to the tenths place (one decimal place). Simple linear regression results for Gender=Male: Dependent Variable: Weight (lbs)Independent Variable: Height (inches)Weight (lbs) = -171.53854 + 4.8317653 Height (inches)Sample size: 4116R (correlation coefficient) = 0.44781967R-sq = 0.20054245Estimate of error standard deviation: 31.744927 Parameter estimates: Parameter Estimate Std.

We intend to estimate the average driving time of a group of commuters. From a previous study, we believe that the average time is 42 minutes with a standard deviation of minutes. We want our 99% confidence interval to have a margin of error of no more than plus or minus minutes. What is the smallest sample size?   Hint: Don’t forget that if you are using the formulas, your answer must be a whole number, rounded up.

Find the critical value for a sample with n = and

SAS Corporation produces and sells one product.   The budgeted selling price per unit is $114. Budgeted unit sales for February is 9,900 units. Each unit of finished goods requires 6 pounds of raw materials. The raw materials cost $4.00 per pound. The direct labor wage rate is $24.00 per hour.
