A manufacturer claims that the thickness of the metal plates it produces is 2.0mm. A quality control specialist regularly checks this claim. On one production run, he took a random sample of n = 8 pieces of metal plates and measured their thickness. He obtained: 2.2 2.0 1.9 1.8 2.1 2.5 2.3 2.3 Test the hypothesis of quality control specialists that HO: μ = 2.0 at 0.01 level of significance. Use 6 steps method. Show all tabulated computation

A fisheries biologist collected a random sample of fish from a lake and conducted a chi-square goodness-of-fit test to see if the distribution of fish changed over time. The table below shows the distribution of fish that were put into the lake when it was originally stocked. Fish Type Trout Bass Perch Sunfish Catfish Percent 25% 25% 20% 15% 15% The biologist found evidence to reject the null hypothesis in favor of the alternative hypothesis. Which of the following represents the alternative hypothesis of the test?
You obtain a t comp of .975 in a two sample independent t test with alpha at .05. Is it significant?
In a completely randomized experimental design, three brands of paper towels were tested for their ability to absorb water. Equal-size towels were used, with four sections of towels tested per brand. The absorbency rating data follow.

In a test of H0: p = 0.4 against H1: p ≠ 0.4, a sample of size 100 produces Z = 1.28 for the value of the test statistic. Thus the p-value (or observed level of significance) of the test is approximately equal to:
