pls help   Many delivery trucks feature a "How Am I Driving?” sticker on the rear bumper, along with a phone number. This sticker allows drivers to report erratic driving by the truck driver or offer a compliment if they like. A dispatcher at the trucking station accepts calls and records information from those who call the phone number. The dispatcher reports that in the past month, 218 calls were received. Of those calls, 178 reported negative driving behaviors by the truck drivers. How might this data-collection method produce bias in obtaining an estimate of all drivers who are satisfied with the company’s truck drivers? This sample may lead to nonresponse bias because many drivers may not call the phone number. This sample may lead to undercoverage bias because some drivers will be more likely to be included in the sample. The sample may lead to response bias because some who call the phone number may not provide a truthful opinion. This sample may lead to voluntary response…

Bullying,” according to noted expert Dan Olweus, “poisons the educational environment and affects the learning of every child.” Bullying and victimization are evident as early as preschool, with the problem peaking in middle school. Suppose you are interested in the emotional well-being of not only the victims but also bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure anxiety in a group of victims and a group of bystanders using a 26-item, 3-point anxiety scale. Assume scores on the anxiety scale are normally distributed and that the variances of the anxiety scores are the same among victims and bystanders. The group of 30 victims scored an average of 21.5 with a sample standard deviation of 10 on the anxiety scale. The group of 27 bystanders scored an average of 25.8 with a sample standard deviation of 9 on the same scale. You do not have any presupposed assumptions about whether victims or bystanders will be more anxious, so you…

Speed Dating: Attributes Listed below are “attribute” ratings made by participants in a speed dating session. Each attribute rating is the sum of the ratings of five attributes (sincerity, intelligence, fun, ambition, shared interests). The listed ratings are from Data Set 18 “Speed Dating” in Appendix B. Use a 0.05 significance level to test the claim that there is a difference between female attribute ratings and male attribute ratings.

HOW TO INPUT IN EXCEL AND JAMOVI A psychologist would like to research if the Hope scale(Synder, et al., 1991) scores differ between those living in City A and City B. The 12-item scale consisted of two subscales: a 6-item agency subscale and a 6-item pathways subscales. Scores on the 12 items were averaged, with higher scores indicating higher levels of hope. The following scores were obtained. Use Student’s t-test for Independent Groups, alpha at .05 2 tail  City A - 43    38    36   38   52   60   58   66   55   63 City B - 62    34    35   52   58    72   57  55   80   67

Do not use Minitab to answer this question. The National Student Survey data described in question 3 were collected for students studying STEM (Science, Technology, Engineering, Maths) subjects part time. The boxplot below (Figure 4) shows the results. Boxplot of approval rating (assessment) * 20.0% 30.0% 40.0% 50.0% 60.0% 70.0% 80.0% 90.0% 100.0 Approval rating (assessment) Figure 4 (a) Explain what the asterisk (*) on the boxplot represents. (b) What can be deduced about the skewness of the data from the boxplot? Explain your answer. (c) A student finds that 85.1% of the STEM students at their own university had positive views of the assessment. They feel this is 'about average' compared with the rest of the sector. Use the boxplot to comment on whether this view seems justified, explaining your answer.

You wish to find evidence that a particular type of team building seminar can improve your employees’ attitudes towards their colleagues. A group of 21 employees take part in the team-building seminar and a questionnaire is used to measure their overall attitudes towards other members of the group both before and after the seminar. For each person, you subtract the score obtained before the seminar from the score obtained after the seminar, and therefore this difference reflects the improvement in their overall attitude. You wish to conduct the test at the .05 level of significance. The mean attitude improvement is 1.45 and the standard deviation of attitude improvement is 4.393. Find the value of the test statistic. Provide your answer as number rounded to 2 decimal places.
