Conduct the appropriate hypothesis test and compute the test statistic.A company that produces fishing line undergoes random testing to see if their fishingline holds up to the advertised specifications. Currently they are producing 30-poundtest line and 20 randomly selected pieces are selected to test the strength. The 20pieces broke with an average force of 29.1 pounds and a sample standard deviationof 2 pounds. Assuming that the strength of the fishing line is normally distributed,perform the appropriate hypothesis test at a 0.05 significance level in order todetermine whether there is sufficient sample evidence to conclude the fishing linebreaks with an average force of less than 30 pounds.Cannot be determined) Yes, because the test statistic is -2.01O No, because the test statistic is -2.01O Yes, because the test statistic is -2.52O No, because the test statistic is -2.52Ouoction 20 /1

Researchers compared two groups of competitive rowers: a group of skilled rowers and a group of novices. The researchers measured the angular velocity of each subject’s right knee, which describes the rate at which the knee joint opens as the legs push the body back on the sliding seat. The sample size ?, the sample mean, and the sample standard deviation for the two groups are given below. Group N x̄ s Skilled 16 4.2 0.6 Novice 16 3.2 0.8 Conduct the test. Provide your significance test formula, test statistic, p-value, and degrees of freedom if applicable. What do you conclude at σ = 0.01?
Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
Kurtis is a statistician who claims that the average salary of an employee in the city of Yarmouth is no more than $55,000 per year. Gina, his colleague, believes this to be incorrect, so she randomly selects 61 employees who work in Yarmouth and record their annual salary. Gina calculates the sample mean income to be $56,500 per year with a sample standard deviation of 3,750. Using the alternative hypothesis H1 : 55.0 appropriate hypothesis test. Round the test statistic to two decimal places and the p-value to three decimal places.

A Two-Sample Hypothesis TestThe mean number of English courses taken in a two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. The males took an average of three English courses with a standard deviation of 0.8. The females took an average of four English courses with a standard deviation of 1.0. Are the means statistically the same?

A manufacturing company produces bearings. One line of bearings is specified to be 1.64 centimeters (cm) in diameter. A major customer requires that the variance of the bearings be no more than .001 cm². The producer is required to test the bearings before they are shipped, and so the diameters of 16 bearings are measured with a precise instrument, resulting in the following values. Assume bearing diameters are normally distributed. Use the data and a = 0.01 to test to determine whether the population of these bearings is to be rejected because of too high a variance. 1.68 1.62 1.63 1.70 1.66 1.63 1.65 1.71 1.64 1.69 1.57 1.64 1.59 1.66 1.63 1.65 Appendix A Statistical Tables (Round your answer to 2 decimal places, e.g. 15.25.)

A sample of 42 observations is selected from one population with a population standard deviation of 4.5. The sample mean is 100.5. A sample of 56 observations is selected from a second population with a population standard deviation of 3.8. The sample mean is 98.5. Conduct the following test of hypothesis using the 0.10 significance level. H₂ H₁ H₂ H₁ H₁ H₂ a. Is this a one-tailed or a two-tailed test? O One-tailed test O Two-tailed test b.
