Problem 9

In Problems 5-12, find the indicated areas. For each problem, be sure to draw a standard normal curve and shade the area that is to be found.

Determine the area under the standard normal curve that lies between

(a) z = -2.04 and z = 2.04

(b) z = -0.55 and z = 0

(c) z = -1.04 and z = 2.76

Step-by-Step Solution:

Step 1 of 5) Find the indicated areas. For each problem, be sure to draw a standard normal curve and shade the area that is to be found. Determine the area under the standard normal curve that lies between (a) z = -2.04 and z = 2.04 (b) z = -0.55 and z = 0 (c) z = -1.04 and z = 2.76 Testing the Significance of Individual Predictor Variables Problem For our model presented in Example 2, test the hypotheses H0: b1 = 0 H0: b2 = 0 vs. vs. H1: b1 ≠ 0 H1: b2 ≠ 0 where b1 is the slope coefficient for the explanatory variable age, and b2 is the slope coefficient for the explanatory variable saturated fat. Approach We will use Minitab to determine the P-values for each explanatory variable. If the P-value is less than the level of significance, we reject the null hypothesis and conclude that the slope coefficient is different from zero. Solution Looking again to the output in Figure 15 on page 697, we see that the test statistic for the explanatory variable age is t0 = 4.18 with a P@value = 0.002.
