Answer:
The required hypothesis the statistician wants to test is: [tex]H_0: \mu=75 [/tex] and [tex]H_a: \mu>75 [/tex].
Step-by-step explanation:
Consider the provided information.
If there is no statistical significance in the test then it is know as the null which is denoted by [tex]H_0[/tex], otherwise it is known as alternative hypothesis which denoted by [tex]H_a[/tex].
A statistician wishing to test a hypothesis that students score at least 75% on the final exam.
That means the null hypothesis should be:
[tex]H_0: \mu=75 [/tex]
Hence, the alternative hypothesis is students score is more that 75%
[tex]H_a: \mu>75 [/tex]
The required hypothesis the statistician wants to test is: [tex]H_0: \mu=75 [/tex] and [tex]H_a: \mu>75 [/tex].
