![]() Using the context of this scenario, explain the meaning of each of following items from the StatCrunch output for the hypothesis test. StatCrunch calculates the P-value for you. This problem has been solved You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Select the Granola column for Treatments in. NOTE: You do not need to double the P-value for this two-tailed test. Select the Rating column for Responses in. (99.7% of people have an IQ between 55 and 145)įor quicker and easier calculations, input the mean and standard deviation into this empirical rule calculator, and watch as it does the rest for you. To analyze the data using repeated measures ANOVA,choose Stat > ANOVA > Repeated Measures. Μ − 3 σ = 100 − 3 ⋅ 15 = 55 \mu - 3\sigma = 100 - 3 \cdot 15 = 55 μ − 3 σ = 100 − 3 ⋅ 15 = 55 Crunch allows users to test hypotheses and display significance levels for two-way tables. (95% of people have an IQ between 70 and 130) Under the Perform option, the Hypothesis tests option is selected by default with a null value of 0 for both the y-intercept and the slope. Select SQFT for the X variable and PRICE for the Y variable. Μ − 2 σ = 100 − 2 ⋅ 15 = 70 \mu - 2\sigma = 100 - 2 \cdot 15 = 70 μ − 2 σ = 100 − 2 ⋅ 15 = 70 To create a simple linear regression model for sales price using square footage, choose the Stat > Regression > Simple Linear menu option. (68% of people have an IQ between 85 and 115) ![]() ![]() Under Perform, choose Confidence interval for p.By default StatCrunch has a value of 0. For this example, in the window containing the hypothesis test results above, choose Options > Edit to reopen the dialog window. Μ + σ = 100 + 15 = 115 \mu + \sigma = 100 + 15 = 115 μ + σ = 100 + 15 = 115 In addition to a hypothesis test, StatCrunch can also create a confidence interval for the proportion of interest. You can enter data right into the spreadsheet by typing. Click on My StatCrunch, then Open my StatCrunch to start a session with new data. Standard deviation: σ = 15 \sigma = 15 σ = 15 Open StatCrunch: Load a data set to analyze or start with an empty set My Data: Shows you the data sets you saved previously My Results: Shows you any results you saved previously. Let's have a look at the maths behind the 68 95 99 rule calculator: For this example we are going to pretend that we tossed a coin 500 times and it landed heads up 265 times. Intelligence quotient (IQ) scores are normally distributed with the mean of 100 and the standard deviation equal to 15. Statistics and Probability questions and answers.
