For this question, I'm not sure how I would solve for the test statistic and the p-value calculation after it? When it is operating correctly, a machine for manufacturing tennis balls produces balls with a mean weight of 57.7 grams. A random sample of eight balls from the last batch produced has the weights listedbelow. Use the Inference for a Mean web app to complete parts a through c. Be sure to use the data in this exercise and not the preloaded data when using the web app.57.6 57.4 57.7 57.6 57.6 57.3 57.957.3a. Find the test statistic and P-value for a test of whether the process is in control against the alternative that the true mean of the process now differs from 57.7.The test statistic is 0.(Round to two decimal places as needed.)

The following data has been provided: 57.6 , 57.4 , 57.7, 57.6 ,57.6, 57.3, 57.9, 57.3 The sample…

What is the p value for the following scenario: Out of 300 male inpatients, there are 195 that have a MCC and out of 450 female inpatients 205 have a MCC.
I need help with just part c. Someone on here already answered it for me but I'm really confused as there are steps missing and I'm not sure what to put in the calculator. " The first quartile separates the lowest 25% of the observations from the higher 75% of the observations. The first quartile is denoted by Q1. The second quartile separates the lower 50% of the observations from the higher 50% of the observations. The second quartile is denoted by Q2.The second quartile is same as median. The third quartile separates the lowest 75% of the observations from the higher 25% of the observations. The third quartile is denoted by Q3. The third quartile can obtained as follows...." Third Quartile is 1 somehow, and I don't understand how it is.
A doctor is concerned that a drug treatment causes people to run a fever. She recruited n=50 participants and gave them the drug treatment. She then measured their body temp 12 hours later. She wants to compare the average temp of her sample to the population average body temp of 98.6 to see if the participants temperature is significantly different. Which statistical test should she 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?
need answer and all the work
You should use a webpage to find the test stat for this problem, Also look at the p-value if the p-value is less than 0.05 there is strong evidence the variables are dependent (there is a difference in proportions). The following data set is the results of some market research were some people were shown one ending (ending 1) and other people were shown a different ending (ending 2), they were asked if they like the product (yes or no) Yes they liked the ending No they did not like the ending ending 1 15 85 ending 2 75 25 Which option below has all the correct options to the chi square test of independence?
