how you find it on the Z-table. Draw the normal curve and shade. What is a critical value for z for a 90% confidence interval? Draw. the normal curve and shade. Why is the z-value 1.96 while in the previous sections we used plus or minus 2 standard deviations for the “pretty sure” measure? Do the “Just Checking” on page 445.

In Fig. 4-5, we have a normal curve in the X’ scale and a standard normal curve in the z scale. The area under the curve within 1, 2, and 3 standard deviation units from the mean is 68.26, 95.54, and 99.74% receptively. Note that great similarity and important difference between Figs. 4-5 and 3-4.

The graph of a normal distribution is a normal curve. Every normal curve has the following characteristics: The mean, median, and mode are equal. They are bell-shaped and symmetrical about the mean. The curve never touches the x-axis, but it comes closer to the x-axis as it gets farther from the mean. The total area under the curve is equal to 1.

is the point with 0.1 area to the right and 0.9 area to the left under the standard Normal curve. Looking at Table A the closest entry with 0.9 to the left is . z*=1.28. 80% of the area under the normal curve lies between -1.28 and 1.28 standard deviations from the mean.
