A researcher was interested in finding out whether students’ sense of belonging in a course differed between students attending classes on campus and students attending classes on Zoom. They recruited five students attending classes on campus and five students attending classes on Zoom to test this. Students were asked to complete a survey measuring how much they felt like they belonged in the course. The scale ranged from 0 (not at all) to 10 (very much). Students’ data, which were non-normal, are provided below.

For healthy adults, the mean pH level is µ = 7.4, a new drug for arthritis has been developed. However, it is thought that this drug may change blood pH. A random sample of 33 patients with arthritis took the drug for three months. Blood tests showed that the sample mean from these 33 patients was a pH of 8.0 and it is known that o = 2.3. (Note, there is no unit for this type of data). Use a = 0.05 level of significance to test the claim that the drug has increased the mean pH level of the blood. If we use the classical approach, what would the criterion (step 3) be? O -1.645 or less O -2.33 or less 1.645 or more O 2.33 or more
Answer the following. Show the solutions. 1. Using the t-table, give the confidence coefficients (t-value) for each of the following. a. n= 12, 99% confidence b. n= 23, 95% confidence
Answer parts d through f please
please answer both the questions within 30 minutes. make sure you answer both the parts else i will give negative ratings for sure. solve both or pass it so that other person can solve both. do not attend only one question.
Firm handshakes seem to be related to shyness. In a sample of n = 12 people who were rated having firm handshakes, their average score on shyness was M = 43 with SS = 1170. Another sample of n = 8 people rated having weak handshakes, their average shyness score was M = 61 with SS =. 990. Use the sample data to estimate how much difference there is in shyness between people with firm vs. weak handshakes. Please do a point estimate and 90% confidence interval estimate.

There exists 2 treatments for a specific illness. One uses pills, and the other infrared pulses. To measure the illness, you measure the level of the a particular marker in the blood; the higher the marker, the worse the disease. Which of the following tests the claim that the infrared pulse treatment improves outcomes better ?
Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values are results for scales of introversion and shyness. High positive scores on each scale indicate high introversion or shyness; and high negative scores indicate low introversion or shyness. Data collected from 10 people as follows: Introversion 4 -7 -1 0 6 7 -4 -9 -5 8 Shyness 11 -7 -1 -3 0 7 -1 -8 -1 5 a) Compute the correlation coefficient relating introversion and shyness scores. b) Find the regression equation which predicts introversion from shyness. c) What introversion score would you predict from a shyness score of 7?
