The mean gas mileage for a hybrid car is 56 miles per gallon. Suppose that the gasoline mileage is approximately normally distributed with a standard deviation of 3.2 miles pergallon. (a) What proportion of hybrids gets over 61 miles per gallon? (b) What proportion of hybrids gets 50 miles per gallon or less? (c) What proportion of hybrids gets between 58and 62 miles per gallon? (d) What is the probability that a randomly selected hybrid gets less than 46 miles per gallon?Click the icon to view a table of areas under the normal curve.(a) The proportion of hybrids that gets over 61 miles per gallon is 0.0594.(Round to four decimal places as needed.)(b) The proportion of hybrids that gets 50 miles per gallon or less is 0.0301(Round to four decimal places as needed.)(c) The proportion of hybrids that gets between 58 and 62 miles per gallon is 0.2342.(Round to four decimal places as needed.)(d) The probability that a randomly selected hybrid gets less than 46 miles per gallon is(Round to four decimal places as needed.)

School-age children should drink approximately 40.5 oz of water per day according to a recent report. Suppose the amounts of water that schoolchildren actually consume in day are approximately normally distributed with a mean of 32.0 oz and a standard deviation of 7.1 oz. What is the probability that a randomly selected student will drink less than the suggested amount of water in a day? If the standard deviation remained the same and the daily water intakes were still normally distributed, how much would the mean need to increase so that only 5% of students drink less than 36 oz per week?
In a Normal distribution, the average is 45 and standard deviation is 12. What is the probability that the outcome is MORE than 40?
A researcher measures the amount of sugar in several cans of the same soda. The mean is 39.01 with a standard deviation of 0.5. The researcher randomly selects a sample of 100. If the researcher wants to find the probability that the sum of the 100 values is greater than 3,910, what is the mean and standard deviation that should be used? mean=??? standard deviation=????
Suppose a professor uses a normal distribution to assign grades in her math class. • She assigns an A to students scoring more than 1.9 standard deviations above the mean. • She assigns an F to students scoring more than 2.2 standard deviations below the mean. She assigns a B to students who Score between 1 and 1.9 standard deviations above the mean. • She assigns a D to students who Score between 1.2 and 2.2 standard deviations below the mean. • All other students get a C. Use the Cumulative Z-Score Table to answer the following questions. The Z-Score Table can be found below by selecting "Read". Write your answer as a percent using 2 decimal places. What percent of the class receives each grade assuming the scores are normally distributed? Hint % will recieve an A % will recieve a B % will recieve a C % will recieve a D % will recieve an F
