The Research hypothesis would be?What type of variable is sodium (ml)?What level of measurement is sodium (ml)?The null hypothesis would be?The alternate hypothesis would be?The value for the statistic is?The p-value is?Will we reject the null hypothesis ?The proportion of variability in blood pressure that we can explain with sodium intake is?The formula for the regression line is?The slope of the regression line is?The y intercept of the regression line is?Two points on the regression line are ? BO will increase how many units for every unit change in sodium ? We will conclude from this problem?

For a project in her physiology class, a student investigated the linear relationship between daily sodium intake and blood pressure. She believed that a high sodium diet would relate to high blood pressure. She found 12 volunteer subjects and measured their sodium intake per day and their blood pressure. Their daily sodium intake (mg) and systolic blood pressures are listed in the table below. (Use a = .05) Sodium BP 4000 132 4500 137 3500 130 5000 148 5200 154 5100 158 6000 165 5400 152 5300 150 6000 167 5500 152 6200 177
