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 ($) Model Price ($) Retail Outlet Deluxe Standard Retail Outlet Deluxe Standard 41 27 40 30 39 30 6. 39 34 3 44 35 35 29 4 38 30 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 = 4 d select Ha = 4 d select Calculate the value of the test statistic. If required enter negative values as negative numbers. (to 2 decimals). The p-value is Select Can you conclude that the price differential is not equal to $10? Select b. What is the 95% confidence interval for the difference between the mean prices of the two models (to 2 decimals)? Use a t-table.
