Question The relationship between United States unemployment and inflation rates during the Covid-19 pandemic. Background The covid-19 pandemic has led to higher unemployment rates in the United States than normal because many people were laid off jobs in response to the pandemic (Al-Fadly, 2020). It is important to analyze how such as sharp increase in unemployment affected inflation in relation to how unemployment have traditionally affected inflation. The overall relationship between unemployment and inflation has traditionally been an inverse one. It is argued that when unemployment rates are higher, the number of individuals who are looking for jobs usually becomes higher than the number of job positions that are available (Putnam & Azzarello, 2015). In such a situation, employers tend to pay lower wages because there is abundance of workers which naturally leads to a lower wage inflation. This study will examine the relationship between unemployment rates and inflation…
A drug treatment can sometimes be affected by the use of another drug taken concomitantly. This is why doctors and pharmacists routinely ask patients about all the drugs they use, even the ones available over the counter. One study examined the impact of nonsteroidal anti-inflammatory drugs (NSAIDs) on the efficacy of the antidepressant citalopram in clinically depressed individuals. Data from a large clinical trial were reviewed, and clinical remission from depressive symptoms was assessed for individuals who had taken NSAIDs concomitantly and those who had not. The findings are given in the table. NSAID use No NSAID use Remission 182 628 No remission 227 509 How strong is the evidence that concomitant NSAID use lowers the effectiveness of the antidepressant citalopram? Follow the four-step process.
Example 5: A corporation psychologist believes that exercise affects self image. To investigate this possibility, 14 employees of the corporation are randomly selected to participate in a jogging programme. Before beginning the programme, they are given a questionnaire that measure self-image. Then they begin the jogging programme. The programme consists of jogging at a moderately taxing rate for 20 minutes a day, 4 days a week. Each employee's self-image is measured again after 2 months on the programme. The results are shown below (the higher the score, the higher the self-image); a score of 20 is the highest score possible.

Researchers at the University of Virginia randomly assigned 60 four-year-olds to one of three tasks: watch a fast-paced television cartoon, watch a slower-paced educational cartoon, or participate in a drawing activity for a nine-minute period. At the end of the period, the researchers tested the children's "executive function," using various tests intended to measure characteristics such as self-regulation and working memory. These researchers found that those children who watched the fast-paced cartoon scored lower on the different measures of executive function than those children who either watched the educational cartoon or did the drawing activity. [Source: Lillard, A. S. & Peterson, J. (2011). The immediate impact of different types of television on young children's executive function. Pediatrics, 128(4), 644-649.] Suppose you are a cognitive psychologist and want to see whether you would find similar results using a repeated-measures design and focusing on a measure of…

Forecasting movie revenues with Twitter. A study presented at the 2010 IEEE International Conference Intelligence and Intelligent Agent Technology investigated whether the volume of chatter on Twitter.com could be used to forecast the box office revenues of movies. For each in a sample of 24 recent movies, opening weekend box office revenue (in millions of dollars) was measured as well as the movie’s tweet rate (the average number of tweets referring to the movie one week prior to the movie’s release).a. In this study, identify the dependent and independent variables.b. Write the equation of the straight-line.
Penicillin Yields. In Statistics for Experimenters (New York, NY: John Wiley &Sons, Inc., 1978),G. Box, W. Hunter, and J. Hunter describe an experiment to determine the effect on yield of four variants of a process for producing penicillin. A basic material in the production process, corn steep liquor, was known to be quite variable. Five blends of corn steep liquor were obtained, and each blend was divided into four equal parts. The four process variants were randomly assigned to the four parts in each blend. The penicillin yields are given in the following table.
1 (part 1). Does When Food Is Eaten Affect Weight Gain?A study was introduced that examined the effect of light at night on weight gain in mice. In the full study of 27 mice over a four-week period, the mice who had a light on at night gained signiﬁcantly more weight than the mice with darkness at night, despite eating the same number of calories and exercising the same amount. Researchers noticed that the mice with light at night ate a greater percentage of their calories during the day (when mice are supposed to be sleeping). The computer output shown below allows us to examine the relationship between percent of calories eaten during the day, DayPct, and body mass gain in grams, BMGain. A scatterplot with regression line is also shown below (attached image).Pearson correlation of BMGain and DayPct =0.740P-Value =0.000--------------------------------------------------------------The regression equation isBMGain=1.11+0.127DayPct Predictor Coef SE Coef T P Constant 1.113 1.382…
