B: Scores below the top 8% and above the bottom 61%
C: Scores below the top 39% and above the bottom 16%
D: Scores below the top 84% and above the bottom 8%
F: Bottom 8% of scores
Scores on the test are normally distributed with a mean of 65.4 and a standard deviation of 9.7. Find the numerical limits for a D grade. Round your answers to the nearest whole number, if necessary.
The numerical limits for a D grade in psychology can be calculated using the Z-score formula. The cutoff scores are below the top 84% and above the bottom 8%. Using the mean of 65.4 and the standard deviation of 9.7, the numerical limits for a D grade are 52 to 79.
To find the numerical limits for a D grade, we need to determine the cutoff scores. According to the given scheme, a D grade corresponds to scores below the top 84% and above the bottom 8%. To calculate these cutoff scores, we can use the Z-score formula. The Z-score is calculated as the difference between a score and the mean, divided by the standard deviation. Using the Z-score table, we can find the Z-scores corresponding to the top 8% and the bottom 8%. Finally, we can use the Z-score formula to find the corresponding scores for those Z-scores.
Given that the mean is 65.4 and the standard deviation is 9.7, we can calculate the Z-scores:
Z-score for the top 8% = 1.405
Z-score for the bottom 8% = -1.405
Using the Z-score formula, where X is the score, the mean is 65.4, and the standard deviation is 9.7:
X = Z * standard deviation + mean
For the top 8%:
X = 1.405 * 9.7 + 65.4 = 79
For the bottom 8%:
X = -1.405 * 9.7 + 65.4 = 52
Therefore, the numerical limits for a D grade are 52 to 79 (rounded to the nearest whole number).

Answer:
(3,11) or (7,11)
Step-by-step explanation:
A function cannot have the same second number repeated ( forgot the term for the second number) so removing either (3,11) or (7,11) would leave it being a function
Answer:
im just gonna answer so that other dude can get the brainliest
Step-by-step explanation:
but hes right, you cant have the same number in the second spot
