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. Но - = d Select Ha = 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.
