engineer who is studying the tensile strength of a steel alloy intended for use in golf afts knows that tensile strength is approximately normally distributed with s=25 random sample of 25 specimens has a mean tensile strength of x = 3490 psi. Test the hypothesis that the mean strength is NOT 3500 psi by using the p-value. Use α=0.05. Test the hypothesis in part (a) using a two-sided confidence interval on mean tensile strength.

An engineer who is studying the tensile strength of a steel alloy intended for use in golf club shafts knows that tensile strength is approximately normally distributed with o = 60 psi. A random sample of 12 specimens has a mean tensile strength of I = 3450 psi. (a) If the mean strength is 3500 psi, what is the smallest level of significance at which you would be willing to reject the null hypothesis? Use a = 0.01. Round your answer to four decimal places (e.g. 98.7654). The smallest level of significance = i (b) What is the B-error if the true mean is 3470 and a = 0.01? Round your answer to three decimal places (e.g. 98.765). B = i (c) Suppose that you wanted to reject the null hypothesis with probability at least 0.8 if mean strength u = 3470 psi. What sample size should be used? i Save for Later Attempts: 0 of 1 used Submit Answer
Researchers measured the length of time people spend brushing their teeth. For the 154 subjects in their study, the mean was 72.8 seconds with a standard deviation of 23. 5 seconds. Use this information with a 0.10 significance level to test the claim that the mean teeth brushing time was less than 80 seconds. What is/are the critical value(s)?

11% of all Americans suffer from sleep apnea. A researcher suspects that a different percentage of those who live in the inner city have sleep apnea. Of the 344 people from the inner city surveyed, 34 of them suffered from sleep apnea. What can be concluded at the level of significance of αα = 0.01? The test statistic= (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.)
a consumer group claims that the mean acceleration time from 0 to 60 miles per hour for a sedan is 6.3 seconds. A random sample of 33 sedans has a mean acceleration time from 0 to 60 miles per hour is 7.2 seconds. Assume that the population standard deviation is 2.5 seconds.At alpha = 0.05, can you reject the claim?
an extensive study conducted in 1980 concluded that the mean mercury level in oysters from the white bear estuary was 0.020 parts per million (ppm) with a standard deviation σ = 0.022. In 2012, a sample of 48 oysters from the same estuary exhibited a mean mercury concentration of 0.004 ppm. can you conclude that the 2012 mercury concentration is lower than in 1980? use the α = 0.01 level of significance. A). yes. the mercury concentration appears to be lower in 2012 B). No. there is insufficient evidence to conclude that the mercury concentration has decreased from 1980 to 2012 C). there is not enough information to reach a conclusion
SOLVE FOR CRITICAL VALUE Two suppliers manufacture a plastic gear used in a laser printer. The impact strength of these gears measures in foot-pounds is an important characteristic. A random sample of 10 gears from supplier 1 results in x1 = 290 and s1 = 12 while another random sample of 16 gears from the second supplier results in x2 = 321 and s2 = 22. Is there evidence to support the claim that supplier 2 provides gears with higher mean impact strength. Use a =0.04, and assume that both populations are normally distributed with equal variances.Level of significance = 0.04
Suppose the mean IQ score of people in a certain country is 100. Suppose the director of a college obtains a simple random sample of 39 students from that country and finds the mean IQ is 104.5 with a standard deviation of 13.6. Complete parts (a) through (d) below. (a) Consider the hypotheses Ho: µ= 100 versus H,: µ> 100. Explain what the director is testing. Perform the test at the a = 0.10 level of significance. Write a conclusion for the test. Explain what the director is testing. Choose the correct answer below. O A. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually not equal to 100. OB. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually greater than 100. O C. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually not greater than 100. O D. The director is testing if the sample provided sufficient…
A study of working actors looked at age and gender. One sample of 55 male actors had a mean age of 34 and a standard deviation of 3. The other sample included 55 female actors with a mean age of 40 and a standard deviation of 2. Estimate with 95% confidence the difference between the average ages of working male (μ1μ1) and female (μ2μ2) actors. Round answers to the nearest hundredth.< μ1−μ2<
The level of calciumin the blood of healthy young adults follows aNormal distributionwithmean μ = 10milligrams per deciliter and standard deviation = 0.4. A clinicmeasures theblood calcium of 100 healthy pregnant young women at their first visit for prenatal care.The mean of these 100 measurements is ¯ x = 9.8. Is this evidence that the mean calciumlevel in the population of healthy pregnant young women is less than 10? To answer this,test the hypotheses H0 : μ = 10 versus Ha : μ < 10 at the 5% significance level.(a) What is the value of the P-value?(b) Determine which of the following statements is true.• H0 should be rejected.• H0 should not be rejected.• Ha should be rejected.• There is a 5% chance that the null hypothesis is true.

Coke recently hired a consulting firm to see how well their products are doing on the market. In the United States last year, the study found that an average of 5,149 coke products were drank daily with a standard deviation of 252. Recall, pnorm(x, µ, o) = P(Y< x) and qnorm(p, µ, 0) = the pn percentile of the normal distribution that has mean, µ, and standard deviation, O. What is the Z-score of 4,125 cokes products?
