Explanation & Answer
Measure of angles 16, 20 and 11 is 180 degree since they are three internal angles of a triangle.
So to find the measure of angle 11 we can add the other two angles and then subtract sum from 180.
Measure of angle 11 = 180 –(84 + 40) = 56 deg.
Hope this helps.

Moore College of Art and Design Hypothesis Test for a Population Worksheet
ContextA group of 75 college students from a liberal arts college were
randomly sampled and asked about the number of alcoholic drinks they
have in a typical week. The file containing the data is linked below.
The purpose of this study (Links to an external site.) was
to compare the drinking habits of the students at the college to the
drinking habits of college students in general. In particular, the dean
of students, who initiated this study, would like to check whether the
mean number of alcoholic drinks that students at his college have in a
typical week differs from the mean of U.S. college students in general,
which is estimated to be 4.73.VariablesThe number of alcoholic beverages a student consumes in a week.Data: Hypothesis test results:

μ
be the mean number of alcoholic beverages that students
in the liberal arts college drink in a typical week. State the
hypotheses.
Here is a histogram of the data. Can we safely use the t-test with this data? Explain.
Perform the t-test using StatCrunch. (directions)Copy and paste the information from the StatCrunch output window into your initial post.Based on the P-value, state your conclusions in context. Use a 5% level of significance. NOTE: You do not need to double the P-value for this two-tailed test. StatCrunch calculates the P-value for you.Using the context of this scenario, explain the meaning of each of
following items from the StatCrunch output for the hypothesis test.

μ

average amount of alcoholic beverages that students at this college
drink is the same as the national average.5. a) Std. Err. is the standard error, which is an estimate of how far from the actual mean a sample mean is likely to be.b) T-stat is T-score, which is used in a t-test to find evidence/lack
of evidence of a significant difference between population means.c) The P-value measures the likelihood of getting results as extreme
as the sample in a population where the null hypothesis is true.

CompetencyDemonstrate the use of the normal distribution, the standard normal distribution, and the central limit theorem for calculating areas under the normal curve and exploring these concepts in real life applications.ScenarioFrank has only had a brief introduction to statistics when he was in high school 12 years ago, and that did not cover inferential statistics. He is not confident in his ability to answer some of the problems posed in the course.As Frank's tutor, you need to provide Frank with guidance and instruction on a worksheet he has partially filled out. Your job is to help him understand and comprehend the material. You should not simply be providing him with an answer as this will not help when it comes time to take the test.
