Question

How would I properly input this in a Ti-83 plus calculator?

You wish to test the following claim (HaHa) at a significance level of α=0.02α=0.02.      

Ho:μ=75.6Ho:μ=75.6
Ha:μ≠75.6Ha:μ≠75.6

You believe the population is normally distributed, but you do not know the standard deviation.

data
24.3
50.6
8.5

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 =  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 75.6.
   • There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 75.6.
   • The sample data support the claim that the population mean is not equal to 75.6.
   • There is not sufficient sample evidence to support the claim that the population mean is not equal to 75.6.
