Labster Lab Report 1

Please solve part d, e, f, g. In a certain jurisdiction, all students in Grade Three are required to take a standardized test to evaluate their math comprehension skills.The file contains these data resulting from a random sample of n=30 schools within this jurisdiction. From these data you wish to estimate the model Yi=β0+β1Xi+ei where Xi is the percentage of Grade Three students in School i who live below the poverty line and Yi is the average mathematics comprehension score for all Grade Three students in the same school, School i. The observed data for the X variable is labled perbelowpoverty and the observed data for the Y variable is labeled mathscore in the file.Import (either hand type or load the file) data into R Studio, then answer the following questions based on the data.(a) Create a scatterplot of the data. What can you say about the nature of the relationship between the percentage of Grade Three students living below the poverty line in a certain school and the school's…

Solve by hand please (no excel).   Hypothesis testing will consist of four hypothesis tests which you need to complete. each test will require the following: Type of Test: Null Hypothesis: Alternate Hypothesis: SE: Test Statistic: P-value: Decision: Sentence:

O Describe an experimental hypothesis and explain which post hoc test you would use if you find a significant overall effect. Include in your explanation the pros and cons of each test in making your decision.

please answer part b frq style

Part E please

Read it carefully and answer the question add the bottom please?

Hi, I need some help foor this question. Please do not copy with chatgpt. Please write clear I need some explain. The chatgpt is not correct. Thanks!  Rick and Morty accidentally created a highly contagious virus that is capable of killing the aliens on planet Zoinks in under a day. So far, only 8% of the population of Zoinks has been infected. Rick and Morty whipped up a test for the virus, but the test is not perfect: 90% of the time it correctly identifies a healthy alien as not having the virus, but 25% of the time it incorrectly identifies an infected alien as virus-free. One of the aliens on the planet is worried that they may have contracted the virus, so they takes 20 independent tests. Of these 20 tests, 6 indicate that they have the disease and the remaining 14 indicate that they do not. With this information, what is the probability that the alien actually has the virus?  Please First use Bayes' formula, then for the conditional probability, and then need to use binomial…

ASSESSMENT Apply the steps in hypothesis testing for each problem. 1. Two rival manufacturers of penlight batteries claimed that their product lasts longer than the other. Thirty samples of Brand A and thirty-four of Brand B were tested. The following are the lengths of lives of such batteries recorded in hours. Use a = 0.05. Brand A 38 41 42 35 40 36 39 41 43 35 36 38 42 39 40 43 44 39 37 40 42 44 38 37 41 40 38 42 45 41 Brand B 38 40 41 39 40 45 40 38 42 41 40 36 37 41 42 | 40 36 38 | 41 40 43 39 41 40 43 39 38 40 43 44 39 40 | 41 | 42 2. A teacher wants to find out if there is a significant difference in the academic performance of two groups of students. One group meets thrice a week while the other meets twice a week. Below are the final exam scores of the two groups. Use a = 0.01. 3x/wk | 80 | 85 66 | 80 | 77 | 75 | 95 | 66 | 55 | 79 | 85 74 75 65 87 2x/wk 66 98 84 85 56 59 25 53 45 66 | 52
