Claim: u> 80; a =0.05 Sample statistics: x= 83.1, s = 3.7, n = 23
What are the null and alternative hypotheses? Choose the correct answer below.
A
OB. Ho: H#80
OA. H: uS80
Hau > 80
OC. Ho: H=80
HA: H# 80
HA: H= 80
O D. Ho: H2 80
B
What is the value of the standardized test statistic?
The standardized test statistic is. (Round to two decimal places as needed.)
