In the EAI sampling problem, the population mean is $51,900 and the population standard deviation is $5,000. When the sample size is n = 20, there is a 0.4085 probability of obtaining a sample mean within +/- $600 of the population mean. What is the probability that the sample mean is within $600 of the population mean if a sample of size 40 is used?
a) If we assume the population mean is 98.60 and the standard deviation is 0.6, what is the probability of a single person having a temperature of 98.25 or less? (Round to four decimal places. This should be the theoretical probability that is calculated, NOT the empirical probability from the simulation.) b) If we assume the population mean is 98.60 and the standard deviation is 0.6, what is the probability of obtaining a sample mean of 98.25 or less from...
In the EAI sampling problem, the population mean is $51,700 and the population standard deviation is $5,000. When the sample size is n = 20, there is a 0.4085 probability of obtaining a sample mean within +/- $600 of the population mean. Use z-table. What is the probability that the sample mean is within $600 of the population mean if a sample of size 40 is used (to 4 decimals)? What is the probability that the sample mean is within...
The population mean is $51,300 and the population standard deviation is $5,000.
