- A researcher selects a sample of international students and provides them with extra support to pursue their educational goals. The graduation rates for the sample is compared to the graduation rates for international students overall. In this study design, what are the null and alternative hypotheses? answer should be in the form of 2 complete sentences.Do sit down restaurant franchises and fast food franchises differ significantly in stock price? Specifically, is the average stock price for sit-down restaurants different from the average stock price for fast food restaurants? If sit down restaurants are considered group 1 and fast food restaurants are group 2, what are the hypotheses of this scenario?9) In 2015, the average math SAT score for students at South Hanover High School was 520. Five years later, a teacher wants to perform a hypothesis test to determine whether the average math SAT score of students at the school has changed since 2015. The hypotheses are: 12) A state fish hatchery raises trout for stocking streams and lakes. The size of the fish at release time can be controlled to a fair degree by varying the rate of feeding. The target is a mean of 10 ounces; if the fish are too small, those who catch the fish aren't happy. A random sample of 75 fish were weighed at time of release and it was determined that the mean was 9.66 ounces with a standard deviation of 0.86 ounces. Test to determine if the fish being released have a population mean less than 10 ounces at the 0.01 significance level. Ho : H = 520 Ha : µ # 520 Suppose that the results of the sampling lead to acceptance of the null hypothesis. Classify that conclusion as a Type I Error, a Type II Error, or a…
- The zombie apocalypse has broken out! It’s like an episode of the Walking Dead out there! You want to determine if the individuals roaming the streets, looking for brains to eat, are actual zombies. What would be your Type II error, given the following hypotheses. H0: They are not zombies! H1: They are zombies! Group of answer choices A.You find they are not zombies, but they actually are B. You find they are zombies, but they actually are not. C. You find that they are zombies, and in fact, they are D. You accidentally sampled Walking Dead extras, not real zombiesYou may need to use the appropriate appendix table or technology to answer this question. In 2012, seventy percent of Canadian households had an internet connection. A sample of 370 households taken in 2013 showed that 76% of them had an internet connection. We are interested in determining whether or not there has been a significant increase in the percentage of the Canadian households that have internet connections. (a) State the null and alternative hypotheses to be tested. (Enter != for as needed. Let p be the proportion of all Canadian households with internet connections.) Ho: на: (b) Compute the test statistic. (Round your answer to two decimal places.) (c) The null hypothesis is to be tested at the 5% level of significance. Determine the critical value(s) for this test. (Round your answer(s) to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic (d) What do you conclude? Do not reject Ho. We can conclude that there has been a…A hospital claims that the proportion of full-term babies born in the hospital who weigh less than seven pounds is no more than 42%.
