The FDA regulates that fish that are consumed should contain no more than 1.0 mg/kg of mercury. In Florida, bass fish were collected in 24 different lakes to measure the amount of mercury in the fish ('Multi- disciplinary niser activity, 2013). The data for the average amount of mercury in the fish from each lake is in table below. Average mercury level in a lake 0.71 0.15 0.17 0.63 0.43 1.08 0.27 0.5 0.19 1.20 0.94 0.87 0.48 0.44 0.98 0.59 0.28 0.49 1.16 0.25 1.23 0.77 0.73 0.65 For the data shown above, find the following. Round values 3 decimal place (s). Select the correct units for each statistic.
The Trial Urban District Assessment (TUDA) is a government-sponsored study of student achievement in large urban school districts. TUDA gives a mathematics test scored from 0 to 500. A score of 262 is a "basic" mathematics level, and a score of 299 is "proficient." Scores for a random sample of 1100 eighth-graders in Dallas had x = 264 with standard error 1.3. TUDA results for 2019 from the National Center for Education Statistics, at https://www.nationsreportcard.gov. LO 5 DEC 1 S tv ♫ ♫ O Macmillan Learning (c) Is there good evidence that the mean for all Dallas eighth-graders is different from the basic level? F8 OYes, because the sample mean of 264 is not included in the 99% confidence interval. Yes, because the basic level of 262 is not included in the 99% confidence interval. O No, because the basic level of 262 is included in the 99% confidence interval. O No, because the sample mean of 264 is included in the 99% confidence interval. N 1917 66 7 A 72 P GE zoom
What is the value of the test statistic for a test with a null hypothesis that mu = 250, Xbar = 260 the standard error = 5 and n = 100?
A data set includes data from 400 random tornadoes. The display from technology available below results from using the tornado lengths (miles) to test the claim that the mean tomado length is K greater than 2.6 miles. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Click the icon to view the display from technology. Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? OA. Ho: H=2.6 miles H₁: #2.6 miles OC. Ho: H=2.6 miles H₁: 2.6 miles OD. Ho: <2.6 miles H₁: μ=2.6 miles
The Cardiac Care Network in Ontario, Canada, wants to determine whether the wait for by- pass surgery is longer than the wait for angiography. A sample of 539 bypass patients waited, on average, 19 days with standard deviation 10 days; a sample of 847 angiography patients waited, on average, 18 days with standard deviation 9 days. What kind of a test should CCN perform? z-interval to estimate the difference in two proportions t-interval to estimate the difference in two means Chi-square test for association t-test for the difference in two means z-test for the difference in two proportions ANOVA
An advertising agency is studying social media campaigns and how they impact website traffic. The advertising agency states the average increase in website traffic after a social media campaign is greater than 20 percent. If we would like to test the advertising agency's claim with a hypothesis test using a significance level of α = 0.015, what is the rejection region? Use the graph below to show the rejection region. First, move the blue dot to choose the appropriate test (left-, right, or two- tailed). Then, slide the shaded region(s) to represent the rejection region. Provide your answer below:
The local utility company checks a sample of utility bills each month to assure the accuracyof the billing statements. The data in the table below shows the number of incorrect bills(defects) out of a sample of 100 statements each time. Construct a control chart using 3-sigmalimits based on this data. Is the process “in statistical control”?
What is the value of the test statistic for a test with a null hypothesis that mu = 82, Xbar = 85, the standard error = 5 and n = 100?
A researcher claims that the proportion of cars with manual transmission is less than 10%. To test this claim, a survey checked 1000 randomly selected cars. Of those cars, 95 had a manual transmission. The following is the setup for the hypothesis test: {H0: p=0.10 Ha: p<0.10 Find the test statistic for this hypothesis test for a proportion. Round your answer to 2 decimal places. Provide your answer below: Test_Statistic=. _______
State the null and alternative hypotheses for the statistical test described below. Your answer should be an expression composed of symbols: =,≠,<,>,μ,μ1,μ2,p,p1,p2,0.3,ρ,p^,p^1,p^2,r.Testing to see if there is evidence that a proportion is greater than 0.3. H0: vs Ha:
