Assignment 3 - statcrunch. com Problem 1: Null Hypothesis: The null hypothesis for the Chi-square test states that there is no association between maternal high blood pressure and the risk of very low birth weight (VLBW) Chi-Square Test Result: The Chi-square test produced a statistic of x^2= 25 19 with a p-value of < 0 0001 Since the p-value is less than 0 05, we reject the null hypothesis This indicates that there is a

report3 - statcrunch. com 1 Mothers' Blood Pressure vs Low Birthweight A chi-square test of independence was conducted to examine the relation between high blood pressure of mothers and low birth weight The test revealed a significant relation (χ² (1) = 25 19, p < 001) While the phi coefficient (φ = 0 05) reveals a weak association, the relative risk (RR) of 1 51 suggests that the risk of a low birth weight baby
Correlation by eye - StatCrunch The StatCrunch Correlation by eye applet has been designed to help students learn a better understanding of how various data values affect correlation This interactive demonstration generates scatter plots at various correlations This applet allows for the guessing of the sample correlation for various datasets and will give messages based on how far the guess is from the sample correlation
