Government regulations restrict the amount of pollutants that can be released to the atmosphere through industrial smokestacks. To demonstrate that their smokestacksare releasing pollutants below the mandated limit of 8 parts per billion pollutants, REM Industries collects a random sample of 15 readings. The mean pollutant level forthe sample is 7.65 parts per billion with a population standard deviation of 0.9 parts per billion. Do the data support the claim that the average pollutants produced byREM Industries are below the mandated level at a 0.05 significance level? Assume the population of readings is approximately normally distributed.Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.

The given values are:Sample size (n) = 15Sample mean (x̄) = 7.65 parts per billionPopulation…

The mean value of land and buildings per acre from a sample of farms is $1600,with a standard deviation of $300.The data set has a bell-shaped distribution. Assume the number of farms in the sample is 75. Use the empirical rule to estimate the number of farms whose land and building values per acre are between $1300 and $1900.
According to a recent poll, 26% of adults in a certain area have high levels of cholesterol. They report that such elevated levels "could be financially devastating to the regions healthcare system" and are a major concern to health insurance providers. Assume the standard deviation from the recent studies is accurate and known. According to recent studies, cholesterol levels in healthy adults from the area average about 206 mg/dL, with a standard deviation of about 35 mg/dL, and are roughly Normally distributed. If the cholesterol levels of a sample of 40 healthy adults from the region is taken, answer parts (a) through (d). (a) What is the probability that the mean cholesterol level of the sample will be no more than 206? P(y≤206) .500 (Round to three decimal places as needed.) (b) What is the probability that the mean cholesterol level of the sample will be between 201 and 211? P(201

The length in feet of a structural I-beam is normally distributed with a mean of 6 ft and a standard deviation of 1 inch. Quality control requirements demand a beam to be rejected if the length of the beam is more than 1 inch different from the mean. What percentage of the I-beams will be rejected?
In a certain population, triglyceride levels are approximately normally distributed with a mean of 150 mg/DL and a standard deviation of 42 mg/DL. Health experts define a level of 200 mg/DL or more as being high (and unhealthy, presumably). What percentage of this population would be considered to have an unhealthy triglyceride level? On your own piece of paper, draw a diagram, calculate a z-score, show your calculator commands and write your answer as a decimal to four place values. For example, probability = 0.0334 Take a picture of your work and upload where indicated.
To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 45 feet. Assume the population standard deviation is 4.6 feet. The mean braking distance for Make B is 46 feet. Assume the population standard deviation is 4.3 feet. At a= 0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles?

Nationally, the amount of debt from college student loans is exceeded only by mortgage debt and is a significant burden for many students after graduation. This photo shows the average student loan debt for a recent graduate of 4-year public colleges and universities in each state and Washington D.C. The distribution of the data can be approximated by a normal model with mean u = $28045 and standard deviation = $3604. a) a high school guidance counselor who provides college attendance advice to seniors wants to know the highest 10% of average student loan debt values. Use the normal model to determine the cutoff value for the highest 10% of average student loan debt value.
A water company wants to analyze the the level of a particular contaminant in a water supply. The contaminant level is to be checked at several locations. Assume that the observed contaminant level is normally distributed and that each observation is independent of the others. A scientist measures the contaminant level at 10 different locations in the water supply and finds the mean level of the substance is T = 120 parts per billion (ppb) with standard deviation s = 25 ppb. Estimate the true mean contaminant level in the water supply with a 99% upper confidence bound. Answer requires 2 decimal places accuracy.
A study reported on essential organic molecules and a Normal model can be used to describe these levels in adults. If the mean is 194 mg/dL and a standard deviation is 28, complete the following questions. a) Draw and label the Normal model. b) What percent of adults do you expect to have this essential organic molecule, cholesterol, levels over 210 mg/dL? c) What percent of adults do you expect to have cholesterol levels between 150 and 170 mg/dL? d) Estimate the interquartile range of cholesterol levels. IQR=___________mg/dL e) Above what value are the highest 15% of adults' cholesterol levels? ___________mg/dL
Unfortunately, arsenic occurs naturally in some ground water.† A mean arsenic level of μ = 8.3 parts per billion (ppb) is considered safe for agricultural use. A well in Texas is used to water cotton crops. This well is tested on a regular basis for arsenic. A random sample of 41 tests gave a sample mean of x = 7.3 ppb arsenic, with s = 2.4 ppb. Does this information indicate that the mean level of arsenic in this well is less than 8.3 ppb? Use ? = 0.01. (a) What is the level of significance? State the null hypotheses H0 and the alternate hypothesis H1 . H0 : μ ---Select--- < ≥ ≤ = > ≠ H1 : μ ---Select--- < > ≤ ≥ = ≠ (b) What sampling distribution will you use? Explain the rationale for your choice of sampling distribution. The standard normal, since the sample size is large and σ is known.The Student's t, since the sample size is large and σ is known. The standard normal, since the sample size is large and σ is unknown. The Student's t, since the…
