Research Question: Is there a difference between the average height of male and female basketball players in the club? 28 male and 25 female basketball players from the club were randomly selected. Use the following image to answer the questions below. Carry out an appropriate hypothesis test to answer the above Research Question. Q1) The null and alternative hypotheses are : Choose one from below -H0: μ = 0, H1: μ ≠ 0 -H0: μ = 170, H1: μ ≠ 170 -H0: μm- μf = 167.489, H1: μm- μf ≠ 167.489 -H0: μm- μf = 0, H1: μm- μf ≠ 0 H0: μm- μf = 170.27, H1: μm- μf ≠ 170.27 Q2) What is the assumption you need to make ? Choose one from below -The shape of the histogram indicates that the scores may be from a normal distribution and/or the sample size is reasonably large so the sample mean will be from a normal population -None of these -Since nπnπ and n(1−π)n(1−π) are both ≥5, the Central Limit Theorem applies and we can assume that p arises from a normal distribution -The boxplots…
According to the Centers of Disease Control, about 21% of American young people between the ages of 12 and 19 are obese. A student claims that the students his local schools are in better'shape than the national average, so'their proportion of obese students is less than 21%. Which are the appropriate null and alternative hypotheses for this study? О о: р - 21%, Н: р < 21% O Ho: p = 21%, H: p 21% O Họ: p = 0, HA: P 0 Оно: р - 21%, Нр» 21%
A local police chief claims that 46% of all robbery-related arrests are never prosecuted. A sample of 500 arrests shows that 43% of the arrests were not prosecuted. Using this information, one officer wants to test the claim that the number of arrests that are never prosecuted is below what the chief stated. Is there enough evidence at the 0.05 level to support the officer's claim? A)State the null and alternative hypotheses. B) Find the value of the test statistic. Round your answer to two decimal places. C)Specify if the test is one-tailed or two-tailed. D)Determine the P-value of the test statistic. Round your answer to four decimal places. E)Identify the value of the level of significance. F)Make the decision to reject or fail to reject the null hypothesis. G)State the conclusion of the hypothesis test.

2. Forty-five percent of the entering CSUN freshmen in Fall 2019 were proficient in math. www.csun.edu/counts/new_first_time_freshman.php a. You want to see if the percentage is different for this fall's entering freshmen. Your hypotheses are Ho: На: where p stands for the percentage of freshmen who were proficient in Fall 2019 / this fall. b. Suppose that the null hypothesis is true that the percentage is 45% for this fall. Here is the sampling distribution of the values of p that would be expected if you repeatedly took random samples of 150 freshman entering this fall and found the proportion proficient in math.

A researcher is investigating US resident’s natural disaster preparedness. The researcher wants to test if less than 40% of US residents have a “natural disaster emergency plan”. To test this, the researcher selected a sample of 1000 US residents. Each sample member was asked if they have a “natural disaster emergency plan”. Of the 1000 samples, 371 responded that they did have a “natural disaster emergency plan”. Conduct the appropriate Hypothesis Test using ∝=.05. The steps of the hypothesis test are provided below: Step 1: State the null and alternative hypotheses one would use to test if less than 40% of US residents have a “natural disaster emergency plan”. Step 2: What distribution/model should be use to conduct this hypothesis test?(If using statistical features on your calculator then what test will you use?) Step 3: State rejection rule. Step 4: Provide the p-value. (From you calculator output or explain how you determined it) Step 5: Using ∝=.05, draw a conclusion.…
