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…

What code , in rstudio/markdown or tests would I need to execute this?

A researcher conducts an experiment comparing two treatment conditions and obtains data with 13 scores for each treatment condition.  For all parts below, explain the logic of your answers.a.  If the researcher used an independent-measures design, how many subjects participated in the experiment?b.  If the researcher used a repeated-measures design, how many subjects participated in the experiment.c.  If the researcher used a matched-subjects design, how many subjects participated in the experiment?

Write a scenario of a problem that would be appropriate for an independent test. Do not use any scenarios that are in the course packet. If you base your idea off of another source, you must state the 9. source.

Select the correct choice that completes​ the sentence below.

Maddie conducts a study to see if listening to music helps students learn math.  She surveys a random sample of 250 college sophomores who completed a math class within the past six months.  She asks them to indicate how frequently they listened to music while studying math.  The students also report their final grade in the math class at the end of the semester.   Select the statement below that is false.     There is no placebo in this study.     Maddie conducted an observational study.     A confounding variable could be how often the participants studied math.     The population Maddie studied was 250 college sophomores.

Please answer all of the question in the picture please. THank you!

You may need to use the appropriate technology to answer this question. A survey was conducted to determine whether hours of sleep per night are independent of age. A sample of individuals was asked to indicate the number of hours of sleep per night with categorical options: fewer than 6 hours, 6 to 6.9 hours, 7 to 7.9 hours, and 8 hours or more. Later in the survey, the individuals were asked to indicate their age with categorical options: age 39 or younger and age 40 or older. Sample data follow. Hours of Sleep Age Group 39 or younger 40 or older Fewer than 6 38 36 6 to 6.9 60 57 7 to 7.9 77 75 8 or more 65 92 (a) Conduct a test of independence to determine whether hours of sleep are independent of age. State the null and alternative hypotheses. H0: Hours of sleep per night is mutually exclusive from age.Ha: Hours of sleep per night is not mutually exclusive from age.H0: Hours of sleep per night is independent of age.Ha: Hours of sleep per night is not independent…

Roughly ten percent of elementary schools in California have a system whereby 4th to 6th graders share a common classroom and a single teacher (multi-age, multi-grade classroom). a. Suggest an experimental design that would allow you to assess the effect of learning in this environment. b. Mention some of the threats to internal and external validity C. and how you would attempt to circumvent these.

This is a practice question. Need help understanding this topic not for a grade. Thanks :)

The Mini-Mental State Examination (MMSE) is useful for the detecting dementia in older adults and 65 or older. Consider that the MMSE adjusted on a patient's education level have a sensitivity of 97% and a specificity of 70%. Which one of the statements below is true based on the sensitivity and specificity? Group of answer choices A. A positive test will most likely rule-out dementia B. A positive test will most likely rule in dementia C. A negative test will most likely rule-out dementia D. A negative test will most likely rule in dementia

Consider a question one could have come across in college, career, or personal life. Describe and apply the five steps below. Five Step Process for Hypothesis Testing: Step 1: State the hypothesis to be tested. Step 2: Specify the decision rule. Step 3: Collect data and calculate necessary statistics to test the hypothesis. Step 4: Make a decision. Step 5: Take action based on the decision. An example: Step 1: State the hypothesis to be tested. Ho: I will go to class today, Ha: I will not go to class today. Step 2: Specify the decision rule. If there is a "high" probability of rain, I will not go to class. If P(rain) ≤0.70, I will go to class (Fail to Reject Ho). Step 3: Collect data and calculate necessary statistics to test the hypothesis. Watch the Weather Channel, check local news, check iphone app to collect data. Statistics for today: Weather Channel: P(rain)=0.50 Local News: P(rain)=0.40 iphone app: P(rain)=0.65 Step 4: Make a decision. All of the statistics…

A quality control inspector selects a part to be tested. The part is then declared acceptable, repairable, or scrapped. Then another part is tested.   Find the number of possible of outcomes of this experiment regarding two parts.

Read the scenario below to determine which one of the five areas of construct validity (content, response processes, internal consistency, relationship to other variables and consequences) is of most concern.    Researchers developed a new and different exam for admission into graduate school.  Researchers constructed a Table of Specifications for the new exam.
