A psychologist wants to estimate the amount of math anxiety that the population of high school students experience prior to taking their first algebra course. On the first day of class he asks a sample of 36 students to answer the question, “How anxious do you feel when you know you have to do math problems?” They each responded using a 100-point scale with 1 = not at all anxious and 100 = extremely anxious. The mean reported anxiety score for this sample was 58 with a standard deviation of 30 What is your point estimate in this scenario? 100 58 30 36
The highway department is testing two types of reflecting paint for concrete bridge end pillars. The two kinds of paint are alike in every respect except that one is orange and the other is yellow. The orange paint is applied to 12 bridges, and the yellow paint is applied to 12 bridges. After a period of 1 year, reflectometer readings were made on all these bridge end pillars. (A higher reading means better visibility.) For the orange paint, the mean reflectometer reading was x1 = 9.4, with standard deviation s1 = 2.4. For the yellow paint the mean was x2 = 6.9, with standard deviation s2 = 2.2. Based on these data, can we conclude that the yellow paint has less visibility after 1 year?

A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOS) of major corporations. He believes that the mean systolic blood pressure, u, of CEOS of major corporations is different from 132 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOS of major corporations and finds the mean of the sample to be 138 mm Hg and the standard deviation of the sample to be 18 mm Hg. Based on this information, answer the questions below. What are the null hypothesis (H,) and the alternative hypothesis (H,) that should be used for the test? H u is ? H:u is ? In the context of this test, what is a Type I error? A Type I error is ? the hypothesis that u is ? - when, in fact, u is ? Suppose that the researcher decides to reject the null hypothesis. What sort of error might he be making? ? Submit A Continue
Lucas and Alex began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Lucas took a test in Math and earned a 73.4, and Alex took a test in English and earned a 70.5. Use the fact that all the students' test grades in the Math class had a mean of 74.1 and a standard deviation of 11.3, and all the students' test grades in English had a mean of 60.9 and a standard deviation of 8.1 to answer the following questions.a) Calculate the z-score for Lucas's test grade.z=z=b) Calculate the z-score for Alex's test grade.z=z=
After the analyses, Rosalind found a significant difference in test scores between taking the test somewhere on campus and taking it in the classroom, t(41)=2.02, p=.049. However, Rebecca found no significant difference between those who took the test somewhere on campus and those who took it in the classroom, t(41)=1.68, p=.099. Considering that Rebecca had a larger mean difference between the two conditions than Rosalind, why are their results so different? I think this deals with type I and type II error giving false positive and false negative respectively, but I wanted to know if there could possibly be anything additional.

In Australia, young people aged 18 to 29 have an average of 394 Facebook friends. This population distribution takes only integer values, so it is certainly not Normal. It is also highly skewed to the right. Suppose that = 280 and you take an SRS of 70 Facebook users from this population. Findings from "Yellow social media report 2018.

Hellen has just started a new years competition for her local climbing gym. There are two categories for this competition: singles and group (18 people). The rules are simple, put in the most hours in one months time and you get a guided tour to climb Ten Sleep canyon. She knows from running this competition over the years that the number of hours climbers at her gym spend training during this competiton is approximately normal and their mean competition hours per month in the gym are 24 hrs with a standard devaition of 6 hrs. Singles Distribution: X~N( , ) Group Distribution: x̄~N( , ) The winning single participant last year was in the 97 th percentile.... how many hours did the winner accumulate over the month?

A psychology teacher has given an exam where the highest possible score is 200 points. The mean score for the 30 students in the class is 156 and the standard deviation was 24. Because there was one question that every student answered incorrectly, the teacher decides to add 10 points to every students’ score. After this transformation, what will the mean be?
