Question 1:
Shade: left of value. Drag the blue arrow to the value z = 1.4
Question 2:
From standard normal table we get that for c = 0.2533, P(-0.2533 < z < 0.2533) = 0.2,
Shade: Middle of two values (-0.2533 and +0.2533). Drag one blue arrow to +0.2533 and another one to -0.2533.

Question 15 Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of OC and a standard deviation of 1.00*C. A single thermometer is randomly selected and tested. Let Z represent the reading of this thermometer at freezing. What reading separates the highest 3.18% from the rest? That is, if P(Z > c) = 0.0318, finde °C C Question 16 Sketch the region corresponding to the statement P* -0.9) Shade: Left of value...

Standard Normal distribution.
With regards to a standard normal distribution complete the following: (a) Find P(Z > 0), the proportion of the standard normal distribution above the z-score of 0. (b) Find P(Z <-0.75), the proportion of the standard normal distribution below the Z-score of -0.75 (c) Find P(-1.15<z <2.04). (d) Find P(Z > -1.25). (e) Find the Z-score corresponding to Pso, the 90th percentile value.

For the following test, assume that the two samples are independent simple random samples selected from normally distributed populations and that the population standard deviations are equal (1 = 02) so that the standard error of the difference between means is obtained by pooling the sample variances. A researcher was interested in comparing the amount of time spent studying baboons by women and men from a group of anthropologists. Independent simple random samples of 32 women and 30 men were...
