For each hypothesis test: * Determine the null and alternative hypotheses. [dentify the sample statistics. Specify the meaning of the population parameter being used in the hypotheses. In other words, define p or p. Compute the standardized test statistic. Round to two decimal places. Determine the P-value. Round to three decimal places. Draw a sketch to show the P-value. Make a decision about the hypotheses and interpret the decision regarding the underlying question. 8. An environmentalist collects a liter of water from 10 different locations along the banks of a stream. He measures the amount of dissolved oxygen in each specimen. The table below contains the oxygen levels in the 10 specimens. 4.58 6.55 6.12 4.53 5.45 4.78 5.38 4.52 5.66 5.89 Using this sample, conduct a hypothesis test to determine whether the mean oxygen level of the water in the stream is different than 5 mg. Use a 5% level of significance. Assume the population is normally distributed
