Question 11 1 pts Use the data found in Estuarine Crocodile (Modified).xlsx for the next 5 problems. Head Length was used to predict Body Length. For this data, which variable is the Dependent variable? O Head Length Body Length
Question 12 0.5 pts Input the lower bound of a 95% confidence interval for the slope. (Round to three decimal places.) Question 13 0.5 pts Input the upper bound of a 95% confidence interval for the slope. (Round to three decimal places.)
Question 14 1 pts Based on your lower bound and upper bound from the last two problems, what can you say about B₁? O There is insufficient evidence to reject the null hypothesis. O We are 95% confident the confidence interval will contain the true value of 8₁ O There is a 95% chance the confidence interval will contain the true value of 8₁
Question 15 Say you want to know if boys are more likely than girls to "wait for their missionary". You take a random sample of 57 males and 63 females, all of whom are in a relationship with someone who just left on a mission. You follow-up with them after the mission of their significant other returned home to determine if their relationship continued after the mission. What type of analysis is best suited for this study? 1 sample z-test (sigma known) O 1 sample t-test (sigma unknown) O 2 independent sample t-test O 2 paired sample t-test O ANOVA test for equality of means 1 pts O Test of 1 proportion O Test of 2 proportions O Chi-square test of independence O Regression analysis
