According to onestudy, brain weights of men are normally distributed with a mean of 1.10 kg and a standard deviation of 0.14 kg.
a. Determine the sampling distribution of the sample mean for samples of size 3.
The mean of the sample mean is x= ?
The standard deviation of the sample mean is x= ?
b. Determine the sampling distribution of the sample mean for samples of size 12.
The mean of the sample mean is x= ?
The standard deviation of the sample mean is x= ?
d. Determine the percentage of all samples of three men that have mean brain weights within 0.1 kg of the population mean brain weight of 1.10 kg.
e. Determine the percentage of all samples of twelve men that have mean brain weights within 0.1 kg of the population mean brain weight of 1.10 kg.
