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 more than 6.5 feet tall? Round your response to 4 decimal places. [q1] 85% 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 less than 6.39 feet? Complete the following to state and interpret this probability. The probability is [prob]. (Round to 4 decimal places) If [100s] were chosen from this population, we'd expect about [number] to have a mean height less than 6.39 feet.
