Explanation Given: The following table provided, which is used by a professor for assigning letter grades in a course. Grade Total points A Greater than μ + 3 2 σ B μ + 1 2 σ to μ + 3 2 σ C μ − 1 2 σ to μ + 1 2 σ D μ − 3 2 σ to μ − 1 2 σ F B e l o w μ − 3 2 σ Explanation: Firstly, solving question no. 40 ; Here, x = μ + 3 2 σ . Where, μ = mean mark σ = Standard deviation Now, to find the z − s c o r e for this value of x . The z − s c o r e is provided by, z = x − μ σ = μ + 3 2 σ − μ σ = 3 2 = 1.5 The normal distribution curve is provided as below; The percentage of students getting the grade A will be area to the right of z = 1.5 . The area under the normal curve after z = 1.5 is, From the standard normal distribution table, Now, find the area to the left of the z − s c o r e , So, Area to the left z − s c o r e = 0.93319 . Hence, The area to the right of z − score = 1.0 − 0.93319 = 0 .06681 = 6 .68% That is, 6.68 % students receive grade A . Now, solving question no. 41 ; Here, x = μ + 3 2 σ and x = μ + 1 2 σ . Where, μ = mean mark σ = Standard deviation The z − s c o r e for the two limits is provided by, The z − s c o r e for, x = μ + 3 2 σ , z = x − μ σ = μ + 3 2 σ − μ σ = 3 2 = 1.5 Now, z − s c o r e for x = μ + 1 2 σ , z = x − μ σ = μ + 1 2 σ − μ σ = 1 2 = 0.5 The normal distribution curve is provided as below;
