Directions: Write the word TRUE if the statement is correct and FALSE if the statement is incorrect. 1. When the means are different and the standard deviations are also different (u14 u2 ; 01 # o2 ), the curves are centered at different points and vary in shapes.

IRUE or FAL SE Directions: Write the word TRUE if the statement is correct and FALSE if the statement is 10.The mean, median, and mode coincide at the center. This also means that in a normal incorrect. distribution, or a distribution described by a normal curve, the mean, median, and mode are equal. 1. When the means are different and the standard deviations are also different (u1# u2 ; 01 # 02 ), COMPUTATION: Directions: Find the area or region that corresponds to each of the following z values. (Use the Table of Areas under the Normal Curve which is also known as z-Tabie) the curves are centered at different points and vary in shapes. 2. When the means are not equal, but the standard deviations are equal. (u1 # u2 : o1 =02 ), 1. Find the area to the left of - 2.15 the curves have a similar shape but centered at 2. Find the area to the right of z = 1.25 different points. 3. Find the area to the left of 2 4. Between 0.18 and 3.2 3. When the means are equal, but the standard 5. Between 0 and -1.5 deviations are equal. (p1 = u2 ; 01 # 02 ), the curves are centered at the same point but they have different height and spreads. 4. The total area of the normal curve is 1. 5. A normally distributed random variable with a mean u = 1 and standard deviation o = 2 is called a standard normal variable. 6, The empirical rule is better known as 68% - 95% - 99.70% rule. This rule states that the data in the distribution lies within one (1), two (2), and three (3) of the standard deviation from the mean are approximately 68%, 95%, and 99.70%, respectively. 7. The total area of the normal curve is 2. 8. The shape of a normal probability distribution is circie. 9. The width of the curve is determined by the standard deviation of the distribution.
