A restaurant that bills its house account monthly believes that the average monthlybill is less than $200 per account. A random sample of 36 accounts is selected,resulting in a sample mean of $180 and a standard deviation of 20.Using a level of significance of 0.01, can we conclude that the average monthly bill islower than $200 per account?1. What is Ho and H1?2. What is the Decision Rule? Show graphically, as well.3. What is the computed value of the test statistic?4. What is the decision regarding Ho? What can we conclude?5. Compute and Interpret the p-value.

Consider a value to be significantly low if its z score less than or equal to −2 or consider a value to be significantly high if its z score is greater than or equal to 2. A test is used to assess readiness for college. In a recent year, the mean test score was 21.4 and the standard deviation was 5.4. Identify the test scores that are significantly low or significantly high. What test scores are significantly low? Select the correct answer below and fill in the answer box(es) to complete your choice. A. Test scores that are between ____ and _____. (Round to one decimal place as needed. Use ascending order.) B. Test scores that are less than _____. (Round to one decimal place as needed.) C. Test scores that are greater than _____. (Round to one decimal place as needed.)
Use z-scores to make the following comparison. A high school student took two college entrance exams, scoring 1110 on the SAT and 27 on the ACT. Suppose that SAT scores have a mean of 950 and a standard deviation of 130 while the ACT scores have a mean of 22 and a standard deviation of 4. Assuming the performance on both tests follows a normal distribution, determine which test the student did better on.
Lead concentration in the eggshell of California condors have a mean of 1.8 ppm and a standard deviation of 0.3 ppm. The contamination levels of eggshells are classified as between 1.0 ppm and 2.4 ppm and high the lead concentration is above 2.4. assuming that the lead concentration of eggshells follows a normal distribution answer the following question.
Suppose in a large class, students' grades in a test followed the normal distribution.

A study was conducted to investigate the ages of college students. Let X = the age of a college student 1. Suppose X follows a distribution skewed to the right.What is true about the shape of the distribution of , the mean age X-bar , for a sample of 100 college students? 2. As the sample size increases, how does that affect the mean for the distribution of X-bar? Group of answer choices 3. Which of the following has the smallest standard deviation? I.
