Paint manufacture: Two methods are being considered to increase production of a paint manufacturing process. In a random sample of 63 days, the meandaily production using the first method was 645 tons with a standard deviation of 48 tons. In a random sample of 64 days, the mean daily production using thesecond method was 630 tons with a standard deviation of 41 tons.Part: 0 / 2Part 1 of 2(a) Construct a 99.8% confidence interval for the difference in mean daily production between the two methods. Let u, denote the mean daily productionusing the first method. Use the table to find the critical value and round the answers to the nearest whole number.A 99.8% confidence interval for the difference in mean daily production between the two methods, in tons,isNOV22MacBook Air888FBF5F6F2F3F4%232$%&4579

In a region, the correlation coefficient between corn yield and peanut yield (planted in the same soil, in MT/ha) is 0.9. We also know that the mean and the standard deviation of corn yield is 3.2 and 2.4, respectively. The mean and the standard deviation of peanut yield is 1.8 and 0.72, respectively. Using this information, predict the expected corn yield of a filed with peanut yield of 1.76.
Big babies: The National Health Statistics Reports described a study in which a sample of 310 one-year-old baby boys were weighed. Their mean weight was 24.4 pounds with standard deviation 5.3 pounds. A pediatrician claims that the mean weight of one-year-old boys is greater than 25 pounds. Do the data provide convincing evidence that the pediatrician's claim is true? Use the α = 0.10 level of significance and the P-value method with the TI-84 Plus calculator. Compute the P-value. Round the answer to at least four decimal places. P-value = ____ How do I solve this problem using the TI-84 calculator?
A researcher wonders whether the recession has changed variability in family size in his city. Before the recession, the mean was 3.7 and the standard deviation was 1.76. The researcher randomly selects 41 families from a population that is normally distributed. His sample has a mean of 3.1 and a standard deviation of 1.45. Test the claim that the standard deviation in size has changed at the αα=.05 significance level.
Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD. A random sample of 59 women between the ages of 41 and 45 with no major health problems were studied. The women were classified into one of two groups based upon their level of exercise activity: walking women and sedentary women. The 39 women who walked regularly had a mean BMD of 5.96 with a standard deviation of 1.22. The 20 women who are sedentary had a mean BMD of 4.41 with a standard deviation of 1.02. Which of the following inference procedures could be used to estimate the difference in the mean BMD for these two types of women
The average undergraduate cost for tuition, fees, and room and board for two-year institutions last year was $14,124. The following year, a random sample of 20 two-year institutions had a mean of $17,124 and a standard deviation of $3700. Is there sufficient evidence at the alpha level of 0.05 to conclude that the mean cost has increased. Show 6 steps of hypothesis
