A manufacturer claims that the average tensile strength of thread A exceeds the average tensilestrength of thread B by at least 12 kilograms. To test this claim, 50 pieces of each type of thread were testedunder similar conditions. Type A thread had an average tensile strength of 86.7 kilograms with a standarddeviation of 6.28 kilograms, while type B thread had an average tensile strength of 77.8 kilograms with astandard deviation of 5.61 kilograms.

Many dairy cows now receive injections of? BST, a hormone intended to spur milk production. After the first? injection, a test herd of 61 cows increased their mean daily production from 49 pounds to 59 pounds of milk. The standard deviation of the increases was 3.1 pounds. A researcher wants to estimate the mean increase a farmer could expect from his own cows?
A manufacturer claims that the calling range (in feet) of its 900-MHz cordless telephone is greater than that of its leading competitor. A sample of 15 phones from the manufacturer had a mean range of 1280 feet with a standard deviation of 21 feet. A sample of 10 similar phones from its competitor had a mean range of 1230 feet with a standard deviation of 40 feet. Do the results support the manufacturer's claim? Let μ₁ be the true mean range of the manufacturer's cordless telephone and μ₂ be the true mean range of the competitor's cordless telephone. Use a significance level of a = 0.01 for the test. Assume that the population variances are equal and that the two populations are normally distributed. Step 2 of 4: Compute the value of the t test statistic. Round your answer to three decimal places.
A manufacturer claims that the average tensile strength of thread A exceeds the average tensile strength of thread B by at least 13 kilograms. To test this claim, 51 pieces of each type of thread were tested under similar conditions. Type A thread had an average tensile strength of 89.8 kilograms with a standard deviation of 5.95 kilograms, while type B thread had an average tensile strength of 79.8 kilograms with a standard deviation of 5.37 kilograms. Test the manufacturer's claim using a 0.05 level of significance. Do not assume that the population variances are equal.

The average size of a farm in one county is 162 acres with a standard deviation of 38 acres. The average size of a farm in a second county is 180 acres with a standard deviation of 40 acres. Assume the data were obtained from two samples that had 30 farms each. Can it be concluded that the average size of the farms in the two counties is different? (Let α = 0.05)

A light bulb manufacturer guarantees that the mean life of a certain type of light bulb is at least 754 hours. A random sample of 30 light bulbs has a mean life of 732 hours. Assume the population is normally distributed and the population standard deviation is 62 hours. At a = 0.05, do you have enough evidence to reject the manufacturer's claim?

A potato chip manufacturer produces bags of potato chips that are supposed to have a net weight of 326 grams. Because the chips vary in size, it is difficult to fill the bags to the exact weight desired. However, the bags pass inspection so long as the standard deviation of their weights is no more than 4 grams. A quality control inspector wished to test the claim that one batch of bags has a standard deviation of more than 4 grams, and thus does not pass inspection. If a sample of 28 bags of potato chips is taken and the standard deviation is found to be 5.3 grams, does this evidence, at the 0.025 level of significance, support the claim that the bags should fail inspection? Assume that the weights of the bags of potato chips are normally distributed. Step 1 of 3 : State the null and alternative hypotheses for the test. Fill in the blank below. Ho: σ=4: Ha: σ ⎯⎯ 4
The Merck Manual states that, for healthy adults, the mean number of milliliters of oxygen per deciliter of blood is 19.0. A company that sells vitamins claims that its multivitamin complex will increase the oxygen capacity of the blood. A random sample of 28 adults took the vitamin for six months. After blood tests, it was found that the sample mean was 20.7 ml of oxygen per deciliter of blood with a standard deviation of 6.7ml. a. At the 0.05 level, test the claim that the average oxygen capacity has increased. b. How much power do you have to detect a 3ml difference (from the null) in the average amount of oxygen in the blood? c. What sample size would you need to have 90% power to detect this observed difference?

A study was conducted to determine if there is a difference in average reading speed between students in grade 4 and grade 5. The null hypothesis is that the means are equal, and the alternative hypothesis is that the means are not equal. A sample of 25 grade 4 students had an average reading speed of 300 words per minute with a standard deviation of 40. A sample of 30 grade 5 students had an average reading speed of 325 words per minute with a standard deviation of 35. What is the t-score and p-value for this hypothesis test?
