Suppose you are a researcher and you are interested in determine the consumption behavior of all first year students at Mzumbe University. Due to limited resources you decide to select only 500 students to represent the entire group. Use the stratified sampling with probability proportional to size to identify the number of students from each programme that will be included in the sample. Assume that the total number of students in each degree programme is as indicated in the table below; Course Econ BAF HRM Education Computer No of students 500 800 1000 400 200 Source: Hypothetical data
Selecting the Appropriate Inferential Test: For each of the studies below, please identify the following (or indicate N/A "not applicable" if the feature is not relevant to the design): a) Independent Variable(s) (IVs) and # of levels for any IVs (for Correlation/Regression, identify the predictor and predicted variable rather than IV and DV) b) Dependent Variable (DV) c) Scale of Measurement for the Dependent Variable: (Nominal, Ordinal, Interval, Ratio) for Correlation/Regression please make sure you identify the scale of measurement for both variables d) Appropriate Statistical Test (If it is a Factorial ANOVA, make sure to name the design: e.g., 2 X 2, 2 X 3, etc.)

Magazine Ads. Advertising researchers F. Shuptrine and D. McVicker wanted to determine whether there were significant differences in the readability of magazine advertisements. Thirty magazines were classified based on their educational level—high, mid, or low—and then three magazines were randomly selected from each level. From each magazine, six advertisements were randomly chosen and examined for readability. In this particular case, readability was characterized by the numbers of words, sentences, and words of three syllables or more in each ad. The researchers published their findings in the paper “Readability Levels of Magazine Ads” (Journal of Advertising Research, Vol. 21, No. 5, pp. 45–51). The number of words of three syllables or more in each ad are provided on the WeissStats site. a. Obtain individual normal probability plots and the standard deviations of the samples. b. Perform a residual analysis. c. Use your results from parts (a) and (b) to decide whether conducting a…

A construction company submitted a bid for a large, public construction project. The company’s management initially felt they had a 50-50 chance of getting the project. However, the department to which the bid was submitted subsequently requested additional information on the bid submitted by this company. Past experience indicates that for 75% of the successful bids but only for 40% of the unsuccessful bids the agency requested such additional information. Question: Given that the construction company was asked for additional information, what is the probability that it will get the project?
a. A random sample of 150 approved mortgage applications is selected from a bank's database. Customers of this bank can choose either variable or interest-only mortgages. These mortgage choices have either a 20-year or 30-year term. The data are displayed i table below. Term Type of Mortgage 20-year Total 30-year 25 Variable 45 Interest Only 40 40 Total Use the table above to answer the questions below. i. If an approved application is selected at random, what is the probability that it is a 30-year term application? ii. If an approved application is randomly selected, what is the probability that the mortgage choice is variable and has a term of 20 years or is interest only and has a term of 20 years?
B. Perimeter Shot - A perimeter shot, also known as a mid-range shot, is a jump shot or general field goal attempt that an offensive player can take inside of the three-point line and is worth 2 points. To practice this, Piel has to choose four different shooting spots among the five different spots in where he is comfortable of shooting. In previous games, his shot selection is 5% from the right baseline (Spot 1), 15% from the right elbow (Spot 2), 20% from the top of the key (Spot 3), 25% from the left elbow (Spot 4) and 35% from the left baseline (Spot 5). In this drill, a shooting spot can be selected once, multiple times, or not at all. This drill illustrates a random experiment with distribution. To help Piel decide, below is the partial table for the means and standard deviations of the random variable, Y, or the number of times he shoot the ball in a shooting spot. Shooting Spot E[Y] SD[Y] Spot 1 0.2 0.4359 Spot 2 0.6 0.7141 Spot 3 0.8 0.8000 Spot 4 the mean of 1.4 by will…

15 Projected undernourished individuals. In 2020, The FAO, IFAD, UNICEF, WFP, and WHO published a brief .... NOURISH report on the state of food security and nutrition in the world. There were 687.8 million undernourished people in the world in 2019. One of the sections in the report shows the distribution of these people as shown in the following table: Region Africa Asia Northern America and Europe Oceania Latin America and the Caribbean Percentage of undernourished people (%) 36.4 55.4 0.9 0.4 6.9 a. Describe the variable measured in the table. b. These results were displayed in the form of a pie chart. Reconstruct the pie chart from the information given in the table. c. How many of the 687.8 million undernourished people in the world in 2019 were in Africa? d. As Africa has many third world countries, people might expect Africa to have the highest number of undernour- ished people in the world. Does the information in the pie chart, part b, support this contention? Explain why or…
