You wish to test the following claim (HaHa) at a significance level of α=0.05α=0.05.

Ho:μ=88.4Ho:μ=88.4
Ha:μ≠88.4Ha:μ≠88.4

You believe the population is normally distributed and you know the population standard deviation is σ=10.9σ=10.9. You obtain a sample mean of ¯x=89.6x¯=89.6 for a sample of size n=80n=80.

1. What is the test statistic for this sample?

test statistic = Round to 3 decimal places

2. What is the p-value for this sample?

p-value = Use Technology Round to 4 decimal places.

3. The p-value is…
• less than (or equal to) αα
• greater than αα
4. This test statistic leads to a decision to…
• reject the null
• accept the null
• fail to reject the null
5. As such, the final conclusion is that…
• There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 88.4.
• There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 88.4.
• The sample data support the claim that the population mean is not equal to 88.4.
• There is not sufficient sa
