5.58 The concentration of mercury in a lake has been monitored for a number of years.Measurements taken on a weekly basis yielded an average of 1.20 mg/m (milligrams percubic meter) with a standard deviation of .32 mg/m. Following an accident at a smelter on theshore of the lake, 15 measurements produced the following mercury concentrations.1.601.771.61 1.08 1.07 1.79 1.341.071.451.59 1.43 2.07 1.16 0.85 2.11ES ABOUT POPULATION CENTRAL VALUESa. Give a point estimate of the mean mercury concentration after the accident.b. Construct a 95% confidence interval on the mean mereury concentration afterthe accident. Interpret this interval.c. Is there sufficient evidence that the mean mercury concentration has increasedsince the accident? Use a = .05.d. Assuming that the standard deviation of the mercury concentration is .32 mg/m.calculate the power of the test to detect mercury concentrations of 1.28, 1.32.1.36, and 1.40.

Consider a value to be significantly low if its z score less than or equal to −2 or consider a value to be significantly high if its z score is greater than or equal to 2. A test is used to assess readiness for college. In a recent year, the mean test score was 21.4 and the standard deviation was 5.4. Identify the test scores that are significantly low or significantly high. What test scores are significantly low? Select the correct answer below and fill in the answer box(es) to complete your choice. A. Test scores that are between ____ and _____. (Round to one decimal place as needed. Use ascending order.) B. Test scores that are less than _____. (Round to one decimal place as needed.) C. Test scores that are greater than _____. (Round to one decimal place as needed.)
Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
A statistics class is estimating the mean height of all female students at their college. They collect a random sample of 42 female students and measure their heights. The mean of the sample is 65.3 inches and the sample standard deviation is 5.4 inches. Find the 90% confidence interval for the mean height of all female students in their school? Assume that the distribution of individual female heights at this school is approximately normal. 1. The t value is 1.3025 2. The standard error has a value of -- 3. The margin of error has a value of 4. Find the 90% confidence interval for the mean height of all female students in their school
Use z scores to compare the given values. The tallest living man at one time had a height of 238 cm. The shortest living man at that time had a height of 142.4 cm. Heights of men at that time had a mean of 175.45 cm and a standard deviation of 5.59 cm. Which of these two men had the height that was more extreme? ... Since the z score for the tallest man is z = 0 and the z score for the shortest man is z = the man had the height that was Im- more extreme. (Round to two decimal places.) shortest tallest
A quiz related to digital knowledge was conducted. The quiz had 10 questions and covered topics such as the purpose of browser cookies, phishing scams, and privacy policies. The survey was given to 50 people. The mean score is 4.1 with a standard deviation of 2.6. We want to know if the data provide evidence that the mean score in the population is lower than 5. We will use alpha = 0.05 to make our decision. part a. Is this a one-sided or two-sided test? part b. What is the standard error for this problem? part c. How many degrees of freedom do we have for this problem? part d. What is the test statistic, t, for this problem? Based on your test statistic and degrees of freedom, the p-value will be between what two values? (If you cannot find the exact df in the table, round down to be safe.

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 5.3 parts/million (ppm). A researcher believes that the current ozone level is at an excess level. The mean of 1030 samples is 5.4 ppm. Assume the standard deviation is known to be 1.1. Does the data support the claim at the 0.01 level? Step 4 of 5 : Enter the decision rule.
