The quality of drinking water must be monitored as often as possible during the day for possible contamination. Another variable of concern is the pH level, which measures the alkalinity or the acidity of the water. A pH below 7.0 is acidic while a pH above is alkaline. A pH of 7.0 is neutral. A water-treatment plant has a target pH of 8.0. Based on 10 random water samples, the mean and the standard deviation were found to be 7.3 and 0.6 respectively. Does the sample mean provide enough evidence that it differs significantly from the target mean? Use a = 10%

Problem:
Drinking Water
Drinking water has become an important concern among
people. The quality of drinking water must be monitored
as often as possible during the day for possible
contamination. Another variable of concern is the pH level,
which
easures the alkalinity or the acidity of the water.
A pH below 7.0 is acidic while a pH above is alkaline. A
pH of 7.0 is neutral. A water-treatment plant has a target
pH of 8.0. Based on 10 random water samples, the mean
and the standard deviation were found to be 7.3 and 0.6
respectively. Does the sample mean provide enough
evidence that it differs significantly from the target mean?

Please help with the following question: for the following hypothesis test: H0: μ = 200 H1: μ ≠ 200 a= 0.01 With n=64, pop standard dev=9, sample mean= 196.5, state •The decision rule in terms of the critical value of the test statistics •The calculated value of the test statistic. •The conclusion.
When conducting a hypothesis test, what would it mean if the researcher obtains a negative test statistic? The sample is too small. It’s very unlikely the results would have occurred just by chance alone. The sample statistic is smaller than the claimed population parameter. A mistake was made in terms of calculating the test statistic. The sample statistic is larger than the claimed population parameter.

In this assignment students will demonstrate their understanding of the distribution of means doing all steps of hypothesis testing. For each problem students will write out all steps of hypothesis testing: 1. State the null and research hypotheses. 2. Set the level of risk associated with the null hypothesis. 3. Select the appropriate test statistic. 4. Compute the test statistic value (called the obtained value). 5. Determine the value needed for rejection of the null hypothesis using the appropriate table of critical values for the particular statistic. 6. Compare the obtained value and the critical value. 7. Make your decision. After completing of the steps of hypothesis tests, write out your results in APA format and in easy-to-understand language 3.
