A Likert Scale is a tool used in many sample surveys to collect opinions on a statement. In this exercise you are asked to use a scale that runs from 5=strongly agree 4-agree 3-neither agree nor disagree 2-disagree 1-strongly disagree What sort of data is a Likert Scale, and why?
How is a sample related to a population? Choose the correct answer below. OA. A sample is a subset of a population. OB. A sample is a numerical measure that describes a sample characteristic. OC. A sample is the collection of all outcomes, responses, measurements, or counts.
ou are doing a problem where you have a negative z-score, and you have to look up the proportion of the shaded area in the tail beyond that z-score; in other words, you are shading to the left from your z-score, and looking for the proportion that you shaded. Four “proportions” are given below. Which one is the ONLY one that could potentially be the number you are looking for? (Hint: Think about what you know about proportions: What kind of number are they? And what things can they represent?) Group of answer choices p = 0.3800 p = -0.1500 p = 1.1500 p = 0.5635
In a random sample of seven people, the mean driving distance to work was 22.5 miles and the standard deviation was 5.9 miles. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a 95% confidence interval for the population mean u. Interpret the results. Identify the margin of error. (Round to one decimal place as needed.) Construct a 95% confidence interval for the population mean. (Round to one decimal place as needed.) Interpret the results. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) O A. With % confidence, it can be said that most driving distances to work (in miles) in the population are between the interval's endpoints. O B. It can be said that % of the population has a driving distance to work (in miles) that is between the interval's endpoints. OC. With % confidence, it can be said that the population mean driving distance to work…
Claim: Fewer than 94 % of adults have a cell phone. In a reputable poll of 1119 adults, 87 % said that they have a cell phone. Find the value of the test statistic.
Indicate the statistical test you would conduct. Respondents in a survey of 1,000 households were asked about their travel history. Specifically, they were asked how often they have been to Europe in the past five years (using a ratio scale). People were also classified by interest type (art-lovers, food-lovers, or sports-lovers). The question is whether interest type influences travel history. Two-sample t-test Paired sample t-test One-way ANOVA none of those QUESTION 6 What is the corresponing alternative hypothesis for the scenario in question #5? The three interest types do not differ with regard to the number of times they have been to Europe in the last five years. Interest type and travel to Europe are not related. The number of times people have been to Europe does not depend on interest type. The three interest types differ with regard to the number of times they have been to Europe in the last five years.
Determine whether the statement describes a descriptive or inferential statistic. 59 % of all students at the local university eat out more than twice a week.
