Consider the following hypothesis test: $$H_0: \mu \le 75$$ $$H_a: \mu > 75$$ A random sample of 100 observations yields a sample mean of 80. The population standard deviation is 30. a. What is the value of the test statistic? Note: Round final answer to 3 decimal places. Test statistic: b. Find the p-value. Note: Do not round the p-value when selecting the interval. $$p-value < 0.01$$ $$0.01 \le p-value < 0.025$$ $$0.025 \le p-value < 0.05$$ $$0.05 \le p-value < 0.10$$ $$p-value \ge 0.10$$ c. What is the conclusion to the hypothesis test at the 10% significance level? Reject $$H_0$$, the population mean is greater than 75. Reject $$H_a$$, the population mean is not greater than 75. Do not reject $$H_0$$, the population mean is greater than 75.

a. According to mud program to drill 8 1/2" hole, the mud density should be 15.5 ppg. After few hours of drilling, the mud engineer took a mud sample and measures the density to be 12.1 ppg. At that time, he noticed the height of mud in the tank as 11 ft. 1 bbl = 42 gallons Density of Barite = 35.5 ppg Tank capacity = 5 bbls/ft Density of Bentonite = 20.8 ppg Determine the quantity of barite (in sacks) to change the density? b. Calculate the density (MW) of 15% (by weight) mud?
