An industrial plant claims they discharge less than 1000 gallons of wastewater per hour in the neighboring lake. To test this claim seven random sample are taken which showed sample mean is 1500 gallon per hour. Let the population standard deviation is known to be 415. What type of test is this?
Homework Answers
Answer:
One sample z test for the population mean
Explanation:
For the given hypothesis test scenario, we need to use the one sample z test for the population man because we have to check the claim or hypothesis about population mean and we are given the value for the population standard deviation. If we were not given the value for population standard deviation, then we will use t test instead of z test.

By a local policy, any industrial plant cannot discharge more than 500 gallons of waste water into the local lake in any given hour. A researcher randomly sampled 100 hours when the plant is in production, and record the gallons of waste water discharged. Below is the statistical software print out of the summary statistics: Variable n mean SD Waste 100 512 50 (2.1) The researcher is interested in whether the plant violated the local policy. State the null and...

Could you please let me know which of the below options is correct? We analyze whether the true mean discharge of wastewater per hour from an industrial plan exceeds the company claim of 1000 gallons. For the decision in the one-sided test using alpha = 0.05: a.) If the plant is exceeding the limit, there is only a 5% chance that we will conclude that they are not exceeding the limit. b.) If we reject H0, the probability that it...

QUESTION 6 A researcher claims that the average yearly consumption of soft drinks per person is less than 60 gallons. In a sample of 85 randomly selected people, the mean of the yearly consumption was 58.8 gallons. The standard deviation of the population is 7.5 gallons. At = 0.005, test the researcher's claim.

Floretta, a pitcher, claims that her pitch speed is less than 46 miles per hour, on average. Several of her teammates do not believe her, so she decides to do a hypothesis test, at a 5% significance level, to persuade them. She throws 24 pitches. The mean speed of the sample pitches is 37 miles per hour. Floretta knows from experience that the standard deviation for her pitch speed is 5 miles per hour. H0: μ=46; Ha: μ<46 α=0.05 (significance...
