A simple random sample of 50 adult females is obtained, and the white blood cell count (in cells per microliter) is measured for each of them, with these results: n = 50, sample mean = 6.889 (in million cells per microliter), s = 2.021 (in million cells per microliter). Use a 0.01 significance level to test the claim that the sample is from a population with a mean less than 8.3 (in million cells per microliter), which is often used as the upper limit of the range of normal values. What is the conclusion of the study? * 2 points A. The white blood cell count of the 50 adult females is equal to the mean of the white blood cell count of the population. B. The white blood cell count of the 50 adult females is not equal to the mean of the white blood cell count of the population. C. The white blood cell count of the 50 adult females is less than to the mean of the white blood cell count of the population. D.…

The Office of the University Registrar of Seoul University would like to know if the degree programs in College of Science and Math are equally preferred by students.The test claim that the proportions of the students enrolled are equal in each degree program at alpha=0.05 Using the data on the number of currently enrolled students in each gender (M of F) in each of the four degree programs, fill out the table below and find the: a. Chi-square critical Value b. Chi-square test statistic
A common characterization of obese individuals is that their body mass index is at least 30 [BMI = weight/(height)2, where height is in meters and weight is in kilograms]. An article reported that in a sample of female workers, 269 had BMIs of less than 25, 156 had BMIs that were at least 25 but less than 30, and 121 had BMIs exceeding 30. Is there compelling evidence for concluding that more than 20% of the individuals in the sampled population are obese? (c) What is the probability of not concluding that more than 20% of the population is obese when the actual percentage of obese individuals is 23%? (Round your answer to four decimal places.)
1)Remove the four potential outliers of 0, 0, 8, and 20, and then obtain a new histogram without the outliers. Does the data appear to be normally distributed now? 2)Assuming that the four potential outliers of 0, 0, 8, and 20 are not recording errors, repeat the hypothesis test from part (c) (again setting up the hypothesis test and using either the critical value or p-value approach), and compare your results with that obtained in (c). Did you make a different conclusion? 3)Imagine you know have to make a recommendation/conclusion to the company that hired you: Assuming that the four potential outlies are not recording errors, and looking at the two results above, would you recommend using the first test with the outliers or the second test with the outliers removed? There is no right or wrong answer here, I am interested in what you think and your reasoning.
The mean ± 1 SD of calcium intake (in mg) among 25 females, 12-14 years of age, below the poverty level is 6.56 ± 0.64. Similarly, the mean ± 1 SD of calcium intake among 40 females, 12-14 years of age, above the poverty level is 6.80 ± 0.76. Do we have sufficient evidence to conclude that the mean intake of calcium among females below the poverty level is significantly lower than the calcium intake of females above the poverty level? State the null and alternative hypothesis in mathematical notation Ho: Ha: What is the level of significance to be used? What is the appropriate test statistic? Why? What is the critical region? Compute for the test statistic. Show all your computations below. What is the statistical decision? What is your basis for such decision? How would you conclude your findings? Be specific.
The worldwide market share for a web browser was 20.5% in a recent month. Suppose that a sample of 240 random students at a certain university finds that 60 use the browser. Complete parts (a) through (d) below. Question content area bottom Part 1 a. At the 0.01 level of significance, is there evidence that the market share for the web browser at the university is greater than the worldwide market share of 20.5%? Determine the null and alternative hypotheses. A. H0: π≤0.205; H1: π>0.205 B. H0: π=0.205; H1: π≠0.205 C. H0: π≠0.205; H1: π=0.205 D. H0: π≥0.205; H1: π<
In a sample of 81 adults selected from one town, it is found that 8 of them have been exposed to a particular strain of the flu. At the 0.01 level of significance, you wish to test the claim that the proportion of all adults in the town that have been exposed to this strain of flu is 8%. A)Give the null and alternative hypotheses and state whether this is one or two tailed test. B)Compute test statictic. C) Use the traditional method to decide if you should reject the null hypothesis or not. D) Use the P-value method to decide if you should reject the null hypothesis or not.
An inventor, working at a science tech lab, believes innovations in satellites are increasing. The inventor would like to test the claim that the average number of new ideas for satellite development per month at the science tech lab is over 60 new ideas. Using the computed test statistic of 1.05 and the critical value of 1.28, is there enough evidence for the inventor to reject the null hypothesis? Use the graph below to interpret the critical value. First select the appropriate test type (left-, right-, or two- tailed), then plot the points along the x-axis (for the critical value and test statistic), and use them to choose the appropriate interpretation.
If the sample data are in the critical region with α = 0.01 and Ho is rejected, then one could still reject Ho even if α were changed to 0.05. Is this statement True or False?
