Data from a certain city shows that individuals with more pets tend to have lower blood pressure (BP). From this information alone, we can say that pet ownership and BP are negatively (inversely) correlated. This may or may not be a causal relationship. pet ownership and BP are not related. pet ownership causes BP to be lower. pet ownership and BP are positively related. This may or may not be a causal relationship. OOOO

Determine the necessary sample size. What is the smallest sample size that would be required to estimate the proportion of "reqular vitamin users" to within 0.03 with 90% confidence? (Hint: use a 'worst case scenario' of p=0.50) O 1068 2401 O 1503 1024 752

Using data from the 2008 General Social Survey (GSS), political psychologists were interested in whether speaking a language other than English (1=yes, 2=no) and political views (1=extremely liberal, 7=extremely conservative) would predict attitudes toward the number of immigrants there should be in the United States (1=should be increased a lot, 5=should be reduced a lot). Review the SPSS output and answer the questions below. Describe the correlations between each predictor variable and the outcome variable. Indicate the direction, strength, and pattern of each relationship. Also, indicate whether they were significant.

Fifty-four wild bears were​ anesthetized, and then their weights and chest sizes were measured and listed in a data set. Results are shown in the accompanying display. Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest​ sizes? When measuring an anesthetized​ bear, is it easier to measure chest size than​ weight? If​ so, does it appear that a measured chest size can be used to predict the​ weight?
