Assume that we want 95% confidence that proportion from the sample is within two percentage points of the true population percentage.Determine the point estimate of the population mean and margin of error for the confidence interval. Lower bound is 19, upper bound is 23. The point estimate of the population mean isRefer to the accompanying data set and construct a 95% confidence interval estimate of the mean pulse rate of adult fermales; then do the same for adult males. Compare the results. E Click the icon to view the pulse rates for adult fermales and adult males. Construct a 95% confidence interval of the mean pulse rate for adult fermales. ..... bpm < µBefore every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The Bombardier Dash 8 aircraft can carry 37 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6200 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6200lb/37 = 167.6lb. What is the probability that the aircraft is overloaded? Should the pilot take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 185.47 lb and a standard deviation of 39 lb. make sure to include pdfA California lake has been stocked with rainbow trout. These trout have an average length of 24 inches, with a standard deviation of 3 inches. Someone goes fishing and catches a trout that is 26.25 inches long. Express the length of this trout in standard units, relative to all the trout that were used to stock the lake.

The lengths of the parts must be within certain limits or they will be rejected. A large number of parts were measured and the mean and standard deviation were calculated as 3.1 m and 0.005 m respectively. Assuming this data is normally distributed and 99.7% of the parts were accepted, what are the limits?Use the accompanying paired data consisting of weights of large cars (pounds) and highway fuel consumption (mi/gal). Let x represent the weight of a car and let y represent the highway fuel consumption. Use the given weight and the given confidence level to construct a prediction interval estimate of highway fuel consumption. Use x = 3900 pounds with a 95% confidence level. Click the icon to view the car weight and highway fuel consumption data. Find the indicated prediction interval. mi/galUse the confidence interval to find the estimated margin of error.
