Question
Students at the college agricultural research station are studying egg production of free-range chickens compared with caged chickens. During a 1-week period, a random sample of n1 = 93 free-range hens produced an average of = 11.2 eggs per hen. For the same period, another random sample of n2 = 87 caged hens produced a sample average of = 8.5 eggs per hen. Previous studies show that and Does this indicate the population mean egg production for free-range hens is higher? Use a 5% level of significance
State the hypothesis
Compute the test value
Compute the P-value or find the critical value
Make a decision
Answer the question above
Explanation / Answer
There are two samples.
Create hypotheses as
H0: mu1 = mu2
Ha: mu1 > mu2
Right tailed test for comparison of two sample means.
As std deviation is not given, unable to proceed further.
