The mean water temperature downstream from a discharge pipe at a power plantcooling tower should be no more than 100°F. The water temperature is measured on10 randomly chosen days, and the results are shown below:96.1597.81 97.09 95.0399.46 100.03 99.7498.8595.0898.71a. State the null hypothesis and alternative hypothesis for the above problem.b. Is there evidence that the water temperature is acceptable at 1% level ofsignificance?c. Find the 95% confidence interval for the mean water temperature.d. Check the results obtained in part b) and c} using Rstudio. Write your conclusionbased on the p value obtained in RStudio.

According to our guidelines we can answer only three subparts and rest can be repost.

55°F Clear Heights were measured for a random sample of 15 plants grown while being treated with a particular nutrient. The sample mean and sample standard deviation of those height measurements were 50 centimeters and 12 centimeters, respectively. Assume that the population of heights of treated plants is normally distributed with mean u. Based on the sample, can it be concluded that μ is different from 42 centimeters? Use the 0.10 level of significance. Perform a two-tailed test. Then complete the parts below.

Emissions of sulfur dioxide set off chemical changes in the atmosphere that result in "acid rain." The acidity of liquids is measured by pH on a scale of 0 to 14. Distilled water has pH 7.0, and lower pH values indicate acidity. Normal rain is somewhat acidic, so acid rain is sometimes defined as rainfall with a pH below 5.0. Suppose the pH of rain at one location varies among rainy days according to a Normal distribution with mean 5.30 and standard deviation 0.43. What proportion of rainy days have rainfall with pH below 5.0?
A sample of 314 patients between 38 and 82 were given a drug intended to reduce their level of cholesterol. The results were the mean reduction in cholesterol of 0.94 millimole per liter. Assume the population standard deviation is σ = 0.18. Construct a 98% C.I.
A nutritionist claims that the mean tuna consumption by a person is 3.6 pounds per year. A sample of 90 people shows that the mean tuna consumption by a person is 3.4 pounds per year. Assume the population standard deviation is 1.11 pounds. At α=0.06, can you reject the claim?
A food manufacturer claims that eating its new cereal as part of a daily diet lowers total blood cholesterol levels. The table shows the total blood cholesterol levels (in milligrams per deciliter of blood) of seven patients before eating the cereal and after one year of eating the cereal as part of their diets. Use technology to test the mean difference. Assume the samples are random and dependent, and the population is normally distributed. At a = 0.05, can you conclude that the new cereal lowers total blood cholesterol levels? Patient Total Blood Cholesterol (Before) Total Blood Cholesterol (After) OA. Ho Hd #0 HA Hd=0 OC.

Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Let Z represent the reading of this thermometer at freezing. What reading separates the highest 46.73% from the rest? That is, if P(z > c) = 0.4673, find c. c = °C

Assume that a sample is used to estimate a population mean μμ. Find the margin of error that corresponds to a sample of size 16 with a mean of 68.3 and a standard deviation of 17.9 at a confidence level of 99%.Report the margin of error accurate to one decimal place because the sample statistics are presented with this accuracy.E=
Assume all populations are normally distributed. A travel analyst claims that the mean price of a round trip flight from New York City to Los Angeles is less than $507. In a random sample of 55 round trip flights from NYC to LA, the mean price is $502. Assume the population standard deviation is $111. At α = 0.05, is there enough evidence to support the travel analyst’s claim?
E= Over the years, the mean customer satisfaction rating at a local restaurant has been 65. The restaurant was recently remodeled, and now the management claims the mean customer rating, u, is not equal to 65. In a sample of 32 customers chosen at random, the mean customer rating is 76.2. Assume that the population standard deviation of customer ratings is 22.8. Is there enough evidence to support the claim that the mean customer rating is different from 65? Perform a hypothesis test, using the 0.10 level of significance. (a) State the null hypothesis H, and the alternative hypothesis H,. Ho Aa O
It is estimated that 90% of all 19-year-old men have weights ranging from 117 to 207 lb. Assuming the weight distribution can be adequately modeled by a normal curve and that 117 and 207 are equidistant from the average weight µ, calculate σ.
