- What type of data is this? a) The first, second and third person in a competition. Letter grades: A, B, C, and etc. When a company asks a customer to rate the sales experience on a scale of 1-10. Economic status: low, medium and high. b) Gender (Women, Men) Hair color (Blonde, Brown, Brunette, Red, etc.) Marital status (Married, Single, Widowed) Ethnicity (Hispanic, Asian) c) Age (from 0 years to 100+) Temperature (in Kelvin, but not °C or F) Distance (measured with a ruler or any other assessing device) Time interval (measured with a stop-watch or similar) d) Temperature (°C or F, but not Kelvin) Dates (1066, 1492, 1776, etc.) Time interval on a 12-hour clock (6 am, 6 pm)A data collection method is described to investigate a difference in means. Determine which data analysis method is more appropriate: paired data difference in means or difference in means with two separate groups. In a study to determine whether the color red increases how attractive men find women, one group of men rate the attractiveness of a woman after seeing her picture on a red background and another group of men rate the same woman after seeing her picture on a white background. O Paired data difference in means O Difference in means with two separate groups 16) The mean salary of 5 employees is $41800. The employee salaries have 2 modes: $33000 and $51500. If the median salary gets a $1300 raise, then... Hint: It will help to write down what salaries you know of the five and think about how you normally calculate mean and median.. a) What is the new mean? New Mean = $ b) What is the new median?. New Median = $
- ReAb. a question can influence eyewitness memory. In the study, college students watched a film of ap automobile accident and then were asked questions about what they saw. One group was asked, "About how fast were the cars going when they smashed into each other?" Another group was asked the same question except the verb was changed to "hit" in- stead of "smashed into." The "smashed into" group reported significantly higher estimates of speed than the "hit" group. Suppose a researcher repeats this study with a sample of today's college students and obtains the following results. Estimated Speed Smashed into Hit n 15 n = 15 M = 40.8 M = 34.0 SS = 510 SS = 414 a. Do the results indicate a significantly higher esti- mated speed for the "smashed into" group? Use a one-tailed test with a = .01. b. Compute the estimated value for Cohen's d to measure the size of the effect. the hypothesis test and the measure of effect size would appear in a research report. nort higher 18. In and a classicDoes the attendance in nursery school relate to the thinking skills of a pupil? Assume that 12 pupils were randomly chosen from a Grade 1 class and were given a test on thinking skills.Given the scores below, are these two variables related? For attendance of nursery school, “1” means did attend and “0” did not attend. The data are given below.The operations manager of a company that manufactures tires wants to determine whether there are any differences in the quality of workmanship among the three daily shifts. She randomly selects 499 tires and carefully inspects them. Each tire is either classified as perfect, satisfactory, or defective, and the shift that produced it is also recorded. The two categorical variables of interest are: shift and condition of the tire produced. The data can be summarized by the accompanying two-way table. Perfect Satisfactory Defective Total Shift 1 106 124 2 232 Shift 2 66 85 3 154 Shift 3 36 74 3 113 Total 208 283 8 499 A) This sample has degree of freedom:��= If shift and quality are independent, thenB) With any expected count accurate to 2 decimal places, the expected count in row 1 column 1 is�1,1= C) With any component accurate to 2 decimal places, the component value in row 1 column 1 of the table iscomponent1,1= D) �2 value of this sample is�2= .

- You need to use Stata to look up the dataset and its variables. Use Stata Companion Textbook. (Dataset: NES. Variables: spend8, [pw=nesw].) The NES dataset contains spend8, which records the number of government policy areas where respondents think spending should be increased. Scores range from 0 (the respondent does not want to increase spending on any of the policies) to 8 (the respondent wants to increase spending on all eight policies). The NES, of course, polls a random sample of U.S. adults. In this exercise you will analyze spend8 using the mean and lincom commands. You then will draw inferences about the population mean. (Remember to specify nesw as the probability weight.) The spend8 variable has a sample mean of ______. Make sure you use [pw=nesw] so your results are nationally representative. There is a probability of .95 that spend8’s true population mean falls between a score of ______ at the low end and a score of ______ at the high end. A student researcher…The table below shows the grades of the 20 students of a martial arts class.
