Equation: The random sample population is 500 people who shop for workout programs and equipment. The sample mean of those shopping is that they spend an average of $250.00 per purchase and perchance at least 2 to 3 items for working out and weight lost Assume that the population of consumers is normally distributed with mean M and the standard deviation is 50.
1. Addressed using a single-sample t test
2. Clearly identify the independent and dependent variables you would study.
3. Generate the statistical null and alternative hypotheses.
4. Describe what information the effect size would tell you that the probability value would not.
5. Using realistic numbers for values of degrees of freedom, sample size, and t statistic, report hypothetical results in a few sentences.
The majority of the data is basically distributed if there are enough subjects. For instance, if you collected test scores of only a few honor students, the data will most likely not be normally distributed because you would have a sample that did..
In the game of roulette, a ball is dropped into a spinning wheel, finally landing on one of the wheel's 38 different slots. The wheel has 18 black slots, 18 red slots, 1 green zero, and 1 green double-zero. Suppose the wheel has landed on red 9 ti..
The results for college x was a mean of 5 hours and an estimated population variance of 2 hours: for college y, m= 4, s 2 =1.5; and for college Z, M= 6, s 2 =2.5 what should you conclude? Use the .5 level.
The union for a particular industry has determined that the standard deviation of the daily wages of its workers is $20.. A random sample of 100 workers in this industry has a mean daily wage of $116.
A high school counselor is interested in the percentage of students who will be going to college. She randomly picks 60 students and finds that 53 will be going to college. Use a 95% confidence level to find the population proportion.
At the heart of quantitative research is regression analysis. A regression model simply measures the association of two variables - variation: the dependent variable's observed value
If two randoom samples of sizes n1 = 30 and n2 = 36 are selected independently from two populations with mean 78 and 85, and with standard deviations 12 and 15, respectively, then the standard error of the difference between Xbar1 and Xbar2 are eq..
How many of these new cardholders would you expect to default? What is the standard deviation?
Chocolate bars produced by a certain machine are labeled with 16.0 oz. The distribution of the actual weights of these chocolate bars is Normal with a mean of 16.1 oz and a standard deviation of 0.1 oz. A chocolate bar is considered underweight if..
Draw the pmf of the Poisson distribution that results when the parameter α is equal to the following:
Illustrate by computation that, for straight -line regression of Y on x, β1= 0.
Consider the following two columns that describe different types of data: A. Nominal 1. Qualitative B. Discrete 2. Quantitative C. Ordinal D. Continuous. The correctly paired groupings of the two columns is:
