An article gives the price-an estimated average for a 6-ounce can or a 7.06-ounce pouch-for 14 different brands of water-packed light tuna, based on prices paid nationally in supermarkets.1.00 1.91 1.23 0.87 0.67 0.53 1.411.12 0.61 0.66 0.70 0.61 0.60 0.68(a) Find the average price for the 14 different brands of tuna. (Round your answer to two decimal places.)$(b) Find the median price for the 14 different brands of tuna.$(c) Based on your findings in parts (a) and (b), do you think that the distribution of prices is skewed? Explain.More information is needed to determine skewness.O Since the mean is larger than the median, the distribution is skewed to the right.O Since the median is larger than the mean, the distribution is skewed to the left.O Since the mean and median are equal, the distribution is not skewed.

In a study of the effect of subbase thickness on the amount of surface deflection caused by aircraft landing on an airport runway, simulated Boeing 747 landing gear was trafficked across four sections of runway. Then simulated Boeing 777 landing gear was traf- ficked across four sections of runway. The surface deflection for each trial is listed below. 5. Boeing 747 Boeing 777 4.01 3.87 3.72 3.76 4.57 4.48 4.36 4.43 Compute an appropriate 95% confidence interval for the difference in mean surface deflec- tion for a Boeing 777 vs a Boeing 747. State any additional assumptions that you need to make. You may use Minitab or other software for this problem, but you must show enough steps that it is clear that you understand the procedure(s) you are using.
7.1.36-T 34.31%, 5.83 of 17 pts A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 99% confident that his estimate is in error by no more than four percentage points? Complete parts (a) through (c) below.

Round your answer to 2 decimal places. 2. Determine the value of tc. Round your answer to 5 decimal places. 3. Find the margin of error for the confidence interval. Round your answer to 1 decimal place. 4. Construct the confidence interval for birth weights. Enter your answer as an open interval of the form (a,b) and round to the nearest integer. 5. Babies weighing less than 2500 grams are considered to be of low birth weight. Can you conclude that the average birth weight is greater than 2500 grams? O No, the entire confidence interval is below 2500. O Yes, the entire confidence is above 2500. O No conclusions can be drawn since the confidence interval contains 2500.
