A manufacturer claims that the thickness of the metal plates it produces is 1.5 mm. A quality control specialist regularly checks this claim. On one production run, he took a random sample of n = 8 pieces metal plates and measured their thickness. He obtained: 1.2 1.6 1.3 1.4 1.5 1.5 1.7 1.3 Test the hypothesis of quality control specialist's that H0 : μ = 1.5 at 0.

A one-sample t test of Ho: u= 125 against Ha: µ> 125 is carried out based on sample data from a Normal population. The SRS of size n and s = 12.6. What is the P-value of the test in this situation? 15 produced a mean of x = 132.8 A) P= 0.008 B) P> 0.02 C) 0.02
The police chief selects a sample of 50 local police officers from a population of officers with a mean physical fitness rating of 75 ± 8.0 (m ± s) on a 100-point physical endurance rating scale. He measures a sample mean physical fitness rating on this scale equal to 79. He conducts a one–independent sample z test to determine whether physical endurance increased at a .05 level of significance. Compute effect size using Cohen’s d.

Consider the following sample observations on stabilized viscosity of asphalt specimens. 2,762 2,907 3,012 2,813 2,876 Suppose that for a particular application, it is required that true average viscosity be 3,000. Does this requirement appear to have been satisfied? State the appropriate hypotheses. (Use ? = 0.05.) H0: ? > 3,000 Ha: ? < 3,000 H0: ? = 3,000 Ha: ? ≠ 3,000 H0: ? ≠ 3,000 Ha: ? = 3,000 H0: ? < 3,000 Ha: ? = 3,000 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.) t = P-value = What can you conclude? Reject the null hypothesis.

A previous study estimated the value of p to be 0.79. Find the minimum sample size required to ensure that your estimate (p) will be within 0.01 of p with 99.5% confidence. IMPORTANT: Use a critical value that you found with your calculator (not from a table), and round it 3 places after the decimal point before you plug it into a formula and perform your calculations. Do not round-off any other intermediate results. n=

The police chief selects a sample of 49 local police officers from a population of officers with a mean physical fitness rating of 72 ± 7.0 (μ±σ) on a 100-point physical endurance rating scale. He measures a sample mean physical fitness rating on this scale equal to 74. He conducts a one-independent sample z test to determine whether physical endurance increased at a .05 level of significance.
