14) You have a binomial random variable, B , with n = 120 and p = .44. Estimate P( 50 < B < 57 ).
15) Tigers have weights that are N(500, 20 ). ( pounds ) You win 2 tigers. Find the probability that your tigers have an average weight that is more that 510 pounds .
The following information about the Binomial distribution is provided:
The population proportion of success is p = 0.44 and the sample size is n= 120 . We need to compute
The population mean is computed as:
and the population standard deviation is computed as:
Therefore, we get that
The following information about the mean and standard deviation has been provided:
We need to compute. The corresponding z-value needed to be computed is:
Therefore, we get that
