Claim: The mean systolic blood pressure of all healthy adults is less than than 125 mm Hg. Sample data: For 258 healthy adults, the mean systolic blood pressure level is 124.72 mm Hg and the standard deviation is 15.18 mm Hg. The null and alternative hypotheses are Ho: μ = 125 and H₁ : µ< 125. Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as needed.)
A baseline of calibrated length 400.009 m is observed repeatedly with an EDM instrument. After 25 observations, the average of the observed distance is 400.012 m with a standard deviation of ±0.003 m. Is the distance observed significantly different from the distance calibrated at a 0.05 level of significance? Here you must write: 5.1. The two hypothesis. 5.2. The value of the test statistic. 5.3. The rejection region. 5.4. The conclusion.
A simple random sample of size n= 40 is drawn from a population. The sample mean is found to be 103.6, and the sample standard deviation is found to be 21.7. Is the population mean greater than 100 at the a =0.10 level of significance? Determine the null and alternative hypotheses. Ho: H= 100 H: u> 100 Compute the test statistic.

On average, Americans have lived in 4 places by the time they are 18 years old. Is this average more for college students? The 52 randomly selected college students who answered the survey question had lived in an average of 4.18 places by the time they were 18 years old. The standard deviation for the survey group was 0.5. What can be concluded at the αα = 0.05 level of significance?
I. A study reports that teenagers spend 27 hours a week online (www.telegraph.co.uk). A researcher wanted to check if this claim is true. A random sample of 200 teenagers taken showed that they spend an average of 25.7 hours per week online with a standard deviation of 8.2 hours. Perform a hypothesis test with the alternate hypothesis that teenagers spend less than 27 hours per week online. Use c = 0.05. Perform all of the steps outline in your notes and write a complete conclusion in words. Assume the distribution of hours spent online is normally distributed.
You wish to test the following claim (HaHa) at a significance level of α=0.001α=0.001.

A large milling machine produces steel rods to certain specifications. The machine is considered to be running normally if the standard deviation of the diameter of the rods is at most 0.15 millimeters. The line supervisor needs to test the machine is for normal functionality. The quality inspector takes a sample of 25 rods and finds that the sample standard deviation is 0.19. What are the null and alternative hypotheses for the test? A. H0 : σ = 0.0225 and H1 : σ ≠ 0.0225 B. H0 : σ ≥ 0.15 and H1 : σ < 0.15 C. H0 : σ2 > 0.15 and H1 : σ2 ≤ 0.15 D. H0 : σ2 ≤ 0.0225 and H1 : σ2 > 0.0225
The average scores in a pre-final examination scored by under graduate students in the previous year was 63. A tutor, after conducting the weekly tests, wishes to check whether that average has increased this year. For a sample of 70 students, the mean score was 68 with a standard deviation of 15.State the null and the alternative hypotheses. Group of answer choices H0: μ = 63 vs. Ha: μ ≥ 63 H0: μ = 63 vs. Ha: μ ≠ 63 H0: μ = 63 vs. Ha: μ ≤ 63 H0: μ = 63 vs. Ha: μ > 63 H0: μ = 63 vs. Ha: μ < 63
A taxi company claims that its drivers have an average of at least 12.4 years' experience. In a study of 15 taxi drivers, the average experience was 11.2 years. The standard deviation was 2. At a = 0.10, is the number of years' experience of the taxi drivers really less than the taxi company claimed. State the hypotheses and identify the claim.Identify the statistical test to be used. a. Find for the critical value(s). b. Sketch a curve with the rejection and non-rejection region. Computer for the test value. c. Make the decision. Interpret the results.
