Please, need help 

Use a t-test to test the claim about the population mean p at the given level of significance a using the given sample statistics. Assume the population is normally distributed.
Claim: μ > 8200; α = 0.01
Sample statistics: x = 7900, s= 430, n = 23
' '0· PT UL00
Hại H> 8200
Hai µ = 8200
%3D
C. Ho: µ = 8200
Ha: H# 8200
D. Ho: µ2 8200
Ha: µ< 8200
What is the value of the standardized test statistic?
The standardized test statistic is
(Round to two decimal places as needed.)
What is the P-value?
P =
(Round to three decimal places as needed.)
Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below.
O A. Fail to reject Ho. At the 1% level of significance, there is enough evidence to reject the claim.
O B. Reject Họ. At the 1% level of significance, there is not enough evidence to reject the claim.
C. Fail to reject Ho. At the 1% level of significance, there is not enough evidence to reject the claim.
O D. Reject Ho. At the 1% level of significance, there is enough evidence to reject the claim.
