Detailed explanation-1: -If a test’s scores follow a normal curve, most of the grades will fall on either end of the scale.
Detailed explanation-2: -The 68-95-99.7 Rule In the Normal distribution with mean µ and standard deviation : Approximately 68% of the observations fall within of µ. Approximately 95% of the observations fall within 2 of µ.
Detailed explanation-3: -Answer and Explanation: The correct option is C) The mean divides the distribution into two equal areas. Option C is correct because the normal distribution is a symmetric distribution. Its median is equal to the mean and hence, it divides the distribution into two equal parts.
Detailed explanation-4: -When the majority of the data values fall to the left of the mean, a distribution is said to be? A continuous, symmetric, bell-shaped distribution of a variable.
Detailed explanation-5: -The normal curve tests of means and proportions refer to those tests that are basic methods of testing the possible differences between two samples. The normal curve tests of means and proportions can also be referred to as parametric tests under the assumption that the population follows a normal distribution.
