hello i need help with these statistic questions thank you

question 4

Determine the critical valuels) for a onemean ztest. Draw a graph that illustrates your answer. A twotailed test with a = 0.1 1. Click here to View Page 1 of the table of areas under the standard normal curve. Click here to View Page 2 of the table of areas under the standard normal curve. The critical valuejs} is (are) |:. (Round [0 two decimal places as needed. Use a comma to separate answers as needed.) Choose the correct graph of the hypothesis test below. [:1 A. [:3 B. Do not Reject a Reject Do not (41 H0 : reject HI] l O 39 Q 0.11 l ' High school drop-out rates in a certain country have decreased from nearly 17% in 1990-1991 to 10% in 2010-2011. However the rate in rural areas is 19%, nearly double. A pilot program aimed at keeping students in school in rural areas reported that in the first year of operation 298 of the 1763 students that participated in the program had dropped out of high school. Does this provide evidence that the pilot program has been effective? Explain. Use a significance level of a = 0.05. Determine the hypotheses for this test. Choose the correct answer below. O A. Ho: P= 0.19 OB. Ho: P = 0.19 HA: p #0.19 HA: P 0.17 HA: P 0.19 Compute the test statistic. Select the correct choice below, and, if necessary, fill in the answer box to complete your choice. O A. z= (Type an integer or decimal rounded to two decimal places as needed.) O B. The test statistic cannot be calculated. Not all of the assumptions and conditions for a hypothesis test have been met. Calculate the P-value. Select the correct choice below, and, if necessary, fill in the answer box to complete your choice. O A. P-value = (Type an integer or decimal rounded to three decimal places as needed.) O B. The P-value cannot be calculated. Not all of the assumptions and conditions for a hypothesis test have been met.Is there evidence that the pilot program has been effective? Explain. Ho. Since the P-value is a, there sufficient evidence to say that there is a decrease in the dropout rate with the pilot program.Iron is an integral part of many proteins and enzymes that maintain good health. Recommendations for iron were developed by an institute of medicine for a certain region. The recommended dietary allowance (RDA) of iron for adult females under the age of 51 years is 16 milligrams (mg) per day. A hypothesis test is to be performed to decide whether adult females under the age of 51 years are, on average, getting more than the RDA of 16 mg of iron per day. Complete parts (a) through (c). a. Determine the null hypothesis. Ho: H mg (Type an integer or a decimal. Do not round.) b. Determine the alternative hypothesis. Ha: H mg (Type an integer or a decimal. Do not round.) c. Classify the hypothesis test as two tailed, left tailed, or right tailed. The hypothesis test is because the test is deciding whether the population mean is the specified value Ho
