In a random sample of 500 children from Illinois, 143 were undernourished. Use these sample data to answer the following questions. A. Use the five-step hypothesis testing procedure outlined below to determine if there is evidence that the proportion of all children in Illinois who are undernourished is different from 0.5. Use Minitab. If assumptions are met, use the normal approximation method. You should not need to do any calculations by hand, other than checking assumptions. Remember to include all relevant Minitab output and identify your answers to each step

In a study of the accuracy of fast food drive-through orders, one restaurant had 37 orders that were not accurate among 308 orders observed. Use a 0.01 significance level to test the claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable? Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho:p=0.1 H:p0.1 OC. Ho: p#0.1 H,:p=0.1 O D. Ho: p=0.1 H,:p#0.1 Identify the test statistic for this hypothesis test.

The U.S. Postal Service (USPS) is faced with the issue of a large portion of mail (letters and packages) that cannot be delivered because of an illegible or non-existent address. USPS would like to find out if there is any evidence that the proportion of undeliverable mail has significantly decreased since last year when it was 6%. Which of the following are the correct null and alternative hypotheses for this test? Select one: a. Ho: p = 0.06 versus Ha:p> 0.06 b.

A newsletter publisher believes that less than 68 % of their readers own a Rolls Royce. For marketing purposes, a potential advertiser wants to confirm this claim. After performing a test at the 0.05 level of significance, the advertiser failed to reject the null hypothesis. What is the conclusion regarding the publisher's claim?

Use five-step hypothesis testing for each of the following problems.  Number each of the five steps.  You may use the traditional method or the p-value method.   1) Science fiction novels average 250 pages in length.  The average length of 8 randomly chosen novels written by I. M. Wordy was 265 pages in length with a standard deviation of 35.  At  are Wordy's novels significantly longer than the average science fiction novel? Use five-step hypothesis testing. 2) The average monthly cell phone bill was reported to be $50.07 by the U.S. Wireless Industry.  Random Sampling of a large cell phone company found the following monthly cell phone charges (in dollars):                                                                                                                                                                                                                                                   At the 0.01 level of significance, can it be concluded that the average phone bill has…

In a random sample of​ males, it was found that 27 write with their left hands and 210 do not. In a random sample of​ females, it was found that 55 write with their left hands and 454 do not.
