1A company claimed that their N95 face mask has a mean filtration efficiency rate of 95%. A group of student researcher wanted to verify this claim. They bought and testea 40 of their N95 face masks. They found out that the average filtration efficiency rate of these face mask was 90% with a standard deviation of 4%. Test the claim at 5% level of significance and assume that the population is approximately normally distributed.

A single serving bag of Ray's Classic Potato Chips is listed on the package to be 28.3 grams. The manufacturing process for potato chips can vary from bag to bag. The listed weight of the bag of potato chips is the average weight. The weight of a bag of Ray's chips is known to be Normally distributed with a standard deviation of 0.4 grams. Ray's Potato Chips will not sell any bags that are in bottom 4% of all weights. Find the maximum value that would put a randomly selected bag of Ray's chips at the 4th percentile of weights.

It has long been stated that the mean temperature of humans is 98.6 degrees F. However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6 degrees F. They measured the temperatures of 56 healthy adults 1 to 4 times daily for 3 days, obtaining 250 measurements. The sample data resulted in a sample mean of 98.3 degrees F and a sample standard deviation of 0.9 degrees F. Use the P-value approach to conduct a hypothesis test to judge whether the mean temperature of humans is less than 98.6 degrees F at the alpha equals0.01 level of significance.
Two independent groups of students were selected to participate in a study to determine if having video lectures in an online class has an effect on test scores. The students were randomly (SRS) placed into 2 groups, one group was the online class of 30 students with video lectures and the other group was the online class of 33 students without video lectures. The average test score on the online class of 30 students with video lectures was x-bar: 87 with a standard deviation of s = 1.8 and the average test score the online class of 33 students without video lectures x-bar = 86 with a standard deviation of s = 3.2. Is there enough evidence at the 1% level that the test scores of the online class with video lectures are higher than the test scores of the online class without video lectures? Set up the hypothesis testing: a) Ho: u1 = u2 The average test scores of the online class with video lectures are equal to the average test scores of the online class without video lectures. Ha: u1…
A laboratory claims that the mean sodium level, μ , of a healthy adult is 141 mEq per liter of blood. To test this claim, a random sample of 80 adult patients is evaluated. The mean sodium level for the sample is 142 mEq per liter of blood. It is known that the population standard deviation of adult sodium levels is 11 mEq. Can we conclude, at the 0.05 level of significance, that the population mean adult sodium level differs from that claimed by the laboratory? Perform a two-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places, and round your responses as specified in the table. The null hypothesis: H0: The alternative hypothesis: H1: The type of test statistic: (Choose one)ZtChi squareF The value of the test statistic:(Round to at least three decimal places.)

Individual scores for practices towards COFLU-20 are found to be normally distributed with a mean of 3 and a standard deviation of 1.5 over the entire population. The Ministry of Health wishes to use this information to identify individuals whose score on practices towards COFLU20 is in the lower 75%, in order to give them relevant information on the best practices towards COFLU-20. You are asked to assist in calculating the score that the Ministry of Health should use to decide whether an individual should be given the relevant information?

Scores on a certain "IQ" test for 18-25 year olds are normally distributed. A researcher believes that the average IQ score for students at a certain NJ college is less than 110 points, and so wants to test this hypothesis. The researcher obtain a SRS of 45 student IQ scores from school records and found the mean of the 45 results was 108 with a sample standard deviation of 21. The level of significance (alpha) used for this problem is 0.05/ What is the appropriate test statistic (Student must complete by showing by formula using the ap- propriate values in that formula "showing work" and the final answer and appropriate label)? O T test score = (108-110)/(45/sqrt(21)) = -.2037 O I test score = (108-110)/(21/sqrt(45)) = -.639 T test score = (108-110)/(21/sqrt(45)) = .639 I test score = (110-108)/(21/sqrt(45)) = .639
