MORE BENEFITS OF EATING ORGANICUsing specific data, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organicpotatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additionaldata. In this case, we are testingHọ : Po = PcHa: Po > Pcwhere p, and p. represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and thoseeating conventional food, respectively. Use a 5 % significance level.Effect of Organic Soybeans After 5 DaysAfter 5 days, the proportion of fruit flies eating organic soybeans still alive is 0.92, while the proportion still alive eating conventionalsoybeans is 0.86. The standard error for the difference in proportions is 0.023.What is the value of the test statistic?Round your answer to two decimal places.Z =What is the p-value?Round your answer to three decimal places.p-value = iWhat is the conclusion?Is there evidence of a difference?

20 years ago 48% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 253 850 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did 20 years ago? Use the a= 0.01 level of significance Find the test statistic Find the p-value Determine the conclusion for this hypothesis test.

True or False: 1. For a fixed confidence coefficient, increasing the sample size will make the confidence interval estimate shorter. 2. The non-rejection of the null hypothesis means that the null hypothesis is true. 3. Given the target and sampled population are very different from each other, a conclusion based on a sample is better generalized to the sampled population compared to the target population.

A sample of 900 computer chips revealed that 46 % of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 50 % of the chips do not fail in the first 1000 hours of their use. The quality control manager wants to test the claim that the actual percentage that do not fail is different from the stated percentage. Find the value of the test statistic. Round your answer to two decimal places. Answer Tables Keypad
