Kind attention Psydag:
A random sample of size 20 from a normal population with sample mean 42 and sample standard deviation of 6 . To test the hypothesis the population mean 44 at 5% level of significance , find the pvalue and comment
Clarification:
The sample size is 20 which is less than 30. Z tables cannot be used for this problem. It is given that the distirbution is normal with small sample size and hence t distribution should be used. I need some assistance in finding the P value using t distribution.
Can you please throw some light on this particular point.
Thanks for the response. Mrs. Lakshmi
