)Listen The average life of a brand of automobile tires is 30,000 miles, with a standard deviation of 2,000 miles. If a tire is selected and tested, find the probability that it will have a lifetime between 27,000 and 32,000 miles. Assume the variable is normally distributed. Give your answer as a percent rounded to two decimal places (to the nearest hundredth).

Trucks in a delivery fleet travel a mean of 100 miles per day with a standard deviation of 38 miles per day. The mileage per day is distributed normally. Find the probability that a truck drives at least 141 miles in a day. Round your answer to four decimal places.

The average driver spends $54 at the gas station each week with a standard deviation of $8. Assuming that the amount a driver spends on gas follows a normal distribution, solve for the percentage of drivers who spend: 1. More than $40? 2. Less than $30? 3. Between $30 and $40

Assume that thermometer readings are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A thermometer is randomly selected and tested. For the case below, draw a sketch, and find the probability of the reading. (The given values are in Celsius degrees.) Between 1.50 and 2.25 Click to view page 1 of the table. Click to view page 2 of the table. Draw a sketch. Choose the correct graph below. O A. OB. Oc. z=1.50 z=2.25 z=1.50 z=2.25 z=1.50 z=2.25 The probability of getting a reading between 1.50°C and 2.25°C isO. (Round to four decimal places as needed.)

One year consumers spent an average of ​$22 on a meal at a resturant. Assume that the amount spent on a resturant meal is normally distributed and that the standard deviation is ​$3. Complete parts​ (a) through​ (c) below. Between what two values will the middle 95​% of the amounts of cash spent​ fall?

Solve the problem. Round to the nearest tenth. min one region, the September energy consumption levels for single family homes are found to be normally distributed with a mean of 1050 kWh and a standard deviation of 218 kWh. Find which is the consumption level separating the bottom 45% from the top 55%.

Type in your answer below: As in the previous question, female's pulse rates are normally distributed with a mean 74 beats per minute and a standard deviation 12.5 beats per minute. Find the probability that a female has a pulse rate between 60 beats per minute and 70 beats per minute. You can use a calculator or table A-2 in your textbook. Round your answer to three decimal places.

Find SAT Quartiles. SAT scores are reported on a scale from 600 to 2400. The mean is 1498 and the standard deviation is 316. The quartiles of any distribution are the values with cumulative proportions 0.25, and 0.75. What are the quartiles of the distribution of SAT scores?

Calculus The height of 700 boys are found to approximately follow such a distribution, with a mean height of 148 cm and a standard deviation of 19 cm. Find the number of boys with heights between 129 cm and 167 cm.

Assume that the heights of women are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches. If 100 women are randomly selected, find the probability that they have a mean height greater than 63.0 inches.
