Suppose a researcher wants to see if the proportion of college educated adults is higher in New York compared to Florida. The researcher randomly samples 500 adults in New York and found that 196 had a college education, while a random sample of 600 adults in Florida found that 227 had a college education.At the 0.05 level of significance, does the data provide evidence to suggest the proportion of college educated adults is higher in New York than Florida? Step 1: Define the parameter & setup the testStep 2: State the Level of SignificanceStep 3: Find the value of the Test StatisticsStep 4: Find P-Value OR Find Critical ValueStep 5: State Conclusion and why

A Cox proportional hazards model is estimated relating time to psychiatric hospitalization in patients with severe mental illness. The risk factors include age, sex, prior hospitalization for mental illness, and an indicator of bipolar disorder. The parameter estimates and significance levels for the model are shown here. Which of the predictors are statistically significantly associated with time to psychiatric hospitalization? Predictor Parameter Estimate p-value Age, years 0.0045 0.5647 Sex (0 = female, 1 = male) –0.4841 0.0341 Prior hospitalization (0 = no, 1 = yes) 0.3726 0.6178 Bipolar disorder (0 = no, 1 = yes) 0.7561 0.0042 .

A researcher was interested in estimating the relationship between SAT scores and first year GPA. He looked at the data from a university which requires minimum SAT scores of 600 to enter the university (Note. The possible SAT score is between 200-800). The data from this experiment are presented below. Student ID SAT(X) GPA (Y) 1 680 2.4 2 745 2.1 3 670 2.2 4 720 2.5 5 653 2.0 6 710 1.8 7 675 1.8 8 634 2.3 9 690 2.4 10 711 2.3 Mean 688.8 2.18 Variance 1109 0.06 = (X −X)(Y−Y) 3.15 Compute the Pearson correlation (r) and interpret the coefficient in terms of the direction (positive or negative) and strength of the relationship (weak, moderate, or strong) Many previous studies have found that there is a strong positive relationship between SAT score and the first year GPA. Is your conclusion from question (a)…
