Words were displayed on a computer screen with background colors of red and blue. Results from scores on a test of word recall are given below. Use a 0.05 significance level to test the claim that the samples are from populations with the same standard deviation.

The recommended dietary allowance (RDA) of iron for adult females is 18 milligrams (mg) per day. The given iron intakes (mg) were obtained for 45 random adult females. At the 1% significance level, do the data suggest that adult females are, on average, getting less than the RDA of 18 mg of iron? Assume that the population standard deviation is 4.4 mg. Preliminary data analyses indicate that applying the z-test is reasonable. (Note: x = 14.71 mg.) Click here to view the iron intake data.

Can I have two positive numbers with a normal standard distribution? I'm stuck. Please help. Thank you.
As part of your work for an environmental group, you want to see if the mean amount of waste generated per adult in your community is less than the national average of 5 pounds per day. You take a simple random sample of 23 adults in your community and find that they average 4 pounds with a standard deviation of 1.5 pounds. Suppose you know the amount of waste generated per day follows a normal distribution. Test at .10 significance.Round to the fourthH0H0: HAHA: Test Statistic: P-value: Did something significant happen? Select the Decision Rule: There enough evidence to conclude

The number of calories in a 12-oz serving of randomly selected regular and lite beers is recorded and the summarized statistics is below. Is there sufficient evidence to conclude that the mean number of calories for lite beers is the same as that for the regular beers? Use alpha of .1.

Gentle Ben is a Morgan horse at a Colorado dude ranch. Over the past 8 weeks, a veterinarian took the following glucose readings from this horse (in mg/100 ml). 91 88 82 103 97 108 84 91 The sample mean is x ≈ 93.0. Let x be a random variable representing glucose readings taken from Gentle Ben. We may assume that x has a normal distribution, and we know from past experience that ? = 12.5. The mean glucose level for horses should be ? = 85 mg/100 ml.† Do these data indicate that Gentle Ben has an overall average glucose level higher than 85? Use ? = 0.05. (a) What is the level of significance? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two-tailed test? H0: ? = 85; H1: ? > 85; right-tailed H0: ? > 85; H1: ? = 85; right-tailed H0: ? = 85; H1: ? ≠ 85; two-tailed H0: ? = 85; H1: ? < 85; left-tailed (b) What sampling distribution will you use? Explain the rationale for your choice of sampling distribution.…
