The heights оf cоllege bаsketbаll plаyers are nоrmally distributed with a mean of 6.3 feet and a standard deviation of 0.2 feet. If one college basketball player is randomly chosen, what is the probability that the player is less than 5.8 feet tall? Round your response to 4 decimal places. [q1] 90% of college basketball players are between [lower] feet and [upper] feet tall. (Round values to 2 decimal places.) Suppose a random sample of 40 college basketball players is randomly chosen. Describe the sampling distribution of the mean for samples of size 40. Be sure to address the shape, the mean of the sampling distribution and the standard error of the mean. Where rounding is necessary, round to three decimal places. The sampling distribution of the mean is [shape] with a mean of [mean] feet and standard error of [se] feet. What is the probability that a random sample of 40 college basketball players results in a mean height of greater than 6.33 feet? Complete the following to state and interpret this probability. The probability is [prob]. (Round to 4 decimal places) Complete the following sentence to interpret the probability from part 4. If [100s] were chosen from this population, we'd expect about [number] to have a mean height greater than 6.33 feet.
Sаlаries fоr nurses in Cаlifоrnia are nоrmally distributed with a mean of $133,300 and a standard deviation of $14,200. 1. If one nurse in California is chosen, what is the probability that the salary of this nurse is greater than $160,000? Round your response to 4 decimal places. [q1] 2. 82% of nurses in California earn between [lower] and [upper]. Round to the nearest dollar. Suppose a random sample of 50 nurses in California is chosen. 3. Describe the sampling distribution of the mean for samples of size n = 50. Be sure to address the shape, the mean of the sampling distribution and the standard error of the mean. Where rounding is necessary, round to the nearest dollar. The sampling distribution of the mean is [shape] with a mean of [mean] and standard error of [se]. 4. What is the probability that a random sample of 50 nurses in California have a mean salary of greater than $136,000? a. The probability is [prob]. (Round to 4 decimal places) b. if [100s] were chosen from this population, we'd expect about [number] to have a mean price of more than $136,000.
