For all of these questions don't use the p value method instead use the "5 steps of hypothesis testing." Or I will get all of these wrong and I really need the help!!

4) 18.3% of incoming freshmen indicate they will major in business or a related field. A random sample of 350 incoming college freshmen were asked their preference and 65 replied they were considering business as a major. Estimate the true proportion of freshman business majors with 98% confidence.

5) The average length of a prison term in the US for white collar crime is 34.9 months. A random sample of 45 prison terms indicated a mean stay of 35.8 months with a standard deviation for the population of 8.9 months.. At α (alpha) = 0.04, is there sufficient evidence to conclude the average stay differs from 34.9 months?

6) The average 1-ounce chocolate chip cookie contains 110 calories. A random sample of 8 different brands of 1-ounce chocolate chip cookies resulted in the following calories amounts. At the α (alpha) = 0.01 level, is there sufficient evidence that the average calorie content is greater than 110 calories? 100 125 150 160 120 125 145 100

Use the P-value Approach for all hypothesis tests. Assume that all samples are randomly obtained. A person’s protein requirement is the amount of protein they must consume in a day to maintain a stable weight, muscle mass, etc. A group of researchers wanted to know if the mean protein requirement (in grams of protein per day per kilogram of body weight) is the same for young adult males and females. The protein requirement of 10 males and 11 females was...

Use the P-value Approach for all hypothesis tests. Assume that all samples are randomly obtained. The first significant digit in any number is: 1, 2, 3, 4, 5, 6, 7, 8, and 9. Though we may think that each digit would appear with equal frequency, this is not true. Physicist, Frank Benford, discovered that in many situations where counts accumulate over time that the first digit in the count follows a particular pattern. The probabilities of occurrence to the first...
