I need help figuring this out, very confused. 

A manufacturer produces both a deluxe and a standard model of an automatic sander designed for home use. Selling prices obtained
from a sample of retail outlets follow.
Model Price ($)

a. The manufacturer's suggested retail prices for the two models show a $10 price differential. Use a .05 level of significance and test
that the mean difference between the prices of the two models is $10.
Develop the null and alternative hypotheses.
Ho= μd
Select
Ha = µ d Select
Calculate the value of the test statistic. If required enter negative values as negative numbers. Use z-table. (to 2 decimals).
The p-value is Select
Can you conclude that the price differential is not equal to $10?
Select v
b. What is the 95% confidence interval for the difference between the mean prices of the two models (to 2 decimals)?
