a . Explanation The students are assigned to two groups where the students of first group practiced the piece for 15 minutes on four consecutive days and students of second group practiced the piece 60 minutes on the fifth day after the first exposure to the piece. Calculation: Step 1: Null hypothesis and alternative hypothesis are given below: " $ " H 0 : Average efficiency level in experimental group = Average efficiency level in control group H a : Average efficiency level in experimental group ≠ Average efficiency level in control group Step 2: Assumptions for checking the Mann-Whitney test for independent Rank data are as follows : The groups should be independent. The observations should be independent of each other. Each group should have the same shape and distribution. Requirement check : The students of both experimental group and control group have been assigned to two different methods of learning a piece. Each student can be assigned to one group at a time. The both groups have the same shape and distribution. The Mann-Whitney test is a nonparametric test because it makes no assumption about the distributions of the population such that provided data is not normally distributed . Step 3: From the output window, the test statistics is " $ " Z = − 2 b . To determine Determine which test is appropriate to test that the shorts periods of daily practice is an effective method to learn a piece of music and draw a conclusion based on the results.

Question

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
