A knewton.com Question The following data was calculated during a study on customer experience. Use the following information to find the test statistic and p-value at a 10% level of significance: • The claim is that the percent of companies that view customer experience as the most vital component of a growing business is different than 50%. Sample size = 50 companies • Sample proportion = 0.40 Use the table or the curve below to find the test statistic and p-value. For the curve select the appropriate test by dragging the blue point to a right-, left- or two-tailed diagram, then set the sliders. Use the purple slider to set the significance level. Use the black sliders to set the information from the study described above. z 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 |-1.5 0.067 0.0660.064 0.063 0.062 0.061 0.059 o.058 0.057 0.056 -1.40.081 0.0790.078 0.076 0.075 0.074 0.072 0.071 0.069 0.068 |-1.3 0.097 0.095 0.093 0.092 0.090 0.089 0.087 0.085 0.084 0.082 -1.2 0.115…
The Z-score tells you the number of standard deviations away from the mean (and X-μ can be used to find the in what direction) a data value is. The formula: Z Z-score for a single member of the population. Notice X - μ tells you the signed distance the data value (X) is from the mean. When you divide that by the size of each chunk (the standard deviation) you are measuring the distance in units of the size of the standard deviations (how many standard deviations fit in the distance between the data value and the mean) - which gives you the Z-score. σ The formula X = μ+Z. can be used to find the value in the population when given the Z-score (signed number of standard deviations). Notice that Z. tells you how far from the mean the data value is (since Z is the number of standard deviations and is the size of each standard deviation the product tells the total distance). So adding the distance from the mean to the mean gives the location along the number line for the data value. A…

When should I use the One-sample t-test? Remember that some tests, such as chi squared, can be used under various circumstances. The goal of the test changes based on the situation. Pay attention to the specific conditions noted in parenthesis to ensure you are picking the correct goal. A. Test to compare frequency data to a specific population model B. Compares numerical data to a known mean. The null hypothesis is that the mean of the data equals the known mean. C. Test to see if the frequency data from a population fit a discrete probability distribution. D. Compare two treatment groups when a normal distribution cannot be assumed. E. Compare two treatment groups consisting of paired data when the data do not fit the normal distribution. F. Compare two treatments consisting of paired data where a normal distribution can be assumed. G. Compare two treatment groups of independent samples where the data meet the assumption that the data fit the normal distribution. H. Test the fit of…

Answer the question. Show all the steps, not only the final answer. if possible, sketch a little diagram to clearly see the area under the normal curve. 1. A major research study concluded that the mean number of times that adolescents had engaged in vandalism during the previous 12 months was 3.5 times. We believe the true population mean to be less than this. After collecting our own sample of 36 adolescents, we find that the mean number of times they have vandalized property during a l-year period wasX̅ = 2.9 with a standard deviation equal to .7. Perform all ofthe procedures necessary for conducting a hypothesis test based on our assumption. What do you conclude? Set your alpha level at .05.
On a scale of 0 to 10, the student rated her enjoyment of stats as an 8. The average rating among students is 5, and the average spread around that mean is 1.5. I got the z score as 2.0. Can you kindly help with these questions below? What percent of college students enjoy statistics more? What percent of college students enjoy statistics less?
You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately o = 74.3. You would like to be 98% confident that your estimate is within 3 of the true population mean. How large of a sample size is required? Round up to nearest whole number. n =
