Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Round your answer to four decimal places.) USE SALT = 14.2; σ = 3,6 P(8 ≤ x ≤ 12) =

Hayley has 120 apple trees of a certain variety in her orchard. She estimates the population of apples has a mean of 9 seeds per apple with a standard deviation of 2 seeds. The distribution in the number of seeds per apple has a shape that is approximately normal.  The table gives the standard normal distribution. What percent of Hayley's apples have between 5 and 11 seeds? Enter your answer in the box rounded to the tenths place.

Assume that females have pulse rates that are normally distributed with a mean of μ=73.0beats per minute and a standard deviation of σ=12.5 beats per minute.    a. If 1 adult female is randomly​ selected, find the probability that her pulse rate is less than 79beats per minute.   The probability is _____.​(Round to four decimal places as​ needed.)   b. If 16 adult females are randomly​ selected, find the probability that they have pulse rates with a mean less than 79beats per minute.   The probability is ____. (Round to four decimal places as​ needed.)   c. Why can the normal distribution be used in part​ (b), even though the sample size does not exceed​ 30?     A. Since the distribution is of sample​ means, not​ individuals, the distribution is a normal distribution for any sample size.   B. Since the distribution is of​ individuals, not sample​ means, the distribution is a normal distribution for any sample size.   C. Since the mean pulse rate exceeds​ 30, the…

Assume that thermometer readings are normally distributed with a mean of 0 degreesC and a standard deviation of 1.00degreesC. 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 0.50   and 2.00
