Gnu tests a group of six snowboarders with equal snowboarding abilities who each try Board 1 and Board 2 for threehours each. They are asked to rate them on a softness scale of 1-15. [Assume this is safe to treat as interval data.] You are doing a two-tailed test with a=.10. Calculate the test statistic.

What price do farmers get for their watermelon crops? In the third week of July, a random sample of 40 farming regions gave a sample mean of x = $6.88 per 100 pounds of watermelon. Assume that ? is known to be $1.92 per 100 pounds.
4. A teacher gives a reading skills test to a third-grade class of n = 25 at the beginning of the school year. To evaluate the changes that occur during the year, students are tested again at the end of the year. Their test scores showed an average improvement of MD = 12.7 points with s² = 100. a. Which variables are described in this scenario and what are their scales of measurement? b. Which test should you use?

What stats test should be used to solve the following? A positive psychologist compares whether levels of gratitude in a random sample of n = 50 students at her college (M = 40) differ from the mean of college students across the US (μ = 45). A sports psychologist tested the reaction time of 320 college athletes. She found their average reaction time in a controlled task to be .77 seconds (s = 21). She wondered if the college athletes had faster reactions times than college students on average, who typically reacted in 1.23 seconds. A school psychologist obtained a sample of 120 fourth-grade kids who engaged in remote learning only during the COVID-19 pandemic. She found their average anxiety score to be M = 168. He compared that mean to the average anxiety score of fourth-grade children before the pandemic, which was μ = 144, with a ?=12σ=12. Did the sample of kids engaged in remote learning have a significantly different level of anxiety?
Justin wants to know whether a commonly prescribed drug does improve the attention span of students with attention deficit disorder (ADD). He knows that the mean attention span for students with ADD who are not taking the drug is 2.3 minutes long. His sample of 12 students taking the drug yielded a mean of 4.6 minutes. Justin can find no information regarding σx , so he calculated s2x =1.96. a. Identify the independent and dependent variables. b. In a sentence, state the null hypothesis being tested. c. Using symbols, state the null and alternative hypotheses. d. Determine the critical region using a one-tailed test with alpha = .05. e .Conduct the hypothesis test (Do the math and compare the t-critical and t-obtained values). f. State your conclusions in terms of H0 (Should you reject the H0 or fail to reject/accept the H0). g. Based on your analysis, is there a relationship between the drug and attention span?
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?
In a data set with 25 scores, if the value 16 occurs 12 times, what is its relative frequency?
The wrong alternative. One of your friends is testing the effect of drinking coffee on the duration of cold symptoms. The common cold lasts, on average, 6 days. Your friend starts with no expectations as to whether drinking coffee will have any effect on cold duration. After seeing the results of the experiment, in which the average cold duration was less than 6 days, your friend tests a one-sided alternative about the population mean cold duration when drinking coffee, H0: lcoffee = 6 На: Which gives a one-sided P value P = 0.0465. Explain why your friend should have used a two-sided hypothesis. Hcoffee < 6
