The average length of a trout caught from a certain lake is 12.4 inches, with a standard deviation of 1.2 inches. What are the mean and standard deviation of the sampling distribution for samples of size 19?
Homework Answers
Solution :
Given that ,
mean = 
= 12.4
standard deviation = 
= 1.2
n = 19
sample distribution of sample mean is ,
=
= 12.4
sampling distribution of standard deviation
= /
n =1.2 /
19
= 0.275

A random sample of 19 rainbow trout caught at Brainard Lake, Colorado had mean length of x =11.9 inches with a sample standard deviation of s = 2.8 inches. Find a 99% confidence interval for the population mean length of all rainbow trout in this lake.
A random sample of 36 rainbow trout caught at Brainard Lake in Colorado has a mean length of 11.9 inches with a standard deviation of 2.8 inches
A random sample of 36 rainbow trout caught at Brainard Lake in Colorado has a mean length of 11.9 inches with a standard deviation of 2.8 inches. Assuming that the lengths of rainbow trout in this lake are normally distributed, find a 98% confidence interval for the population mean length of all rainbow trout in this lake.
