Suppose a college administrator daims that the true average score on a particular student survey is 4.00. Express in symbolic form the null and alternative hypotheses needed to test the administrator’s claim.
o Ho :/j* 4.00
HA .7/ = 4.00
o H0 .7/= 4.00
HA .7/>4.00
o H0 .7/= 4.00
ha .7/<4.00
o H0 .7/= 4.00
ha .7/ *4.00

For the hypothesis test in Problem 2, suppose that 83 student surveys are collected, and that their mean score was 3.84 with standard deviation 0.51. What is the resulting p-value? (Round your answer to three decimal places; add trailing zeros as needed.)
The p-value * type your answer...

Using the information in Problem 3, identify the appropriate decision for the hypothesis test in Problem 2, along with its interpretation. Use a = 0.10.
