Answer: 0.5%
Step-by-step explanation:
We assume that the test scores in final exam is normally distributed.
Given : Mean :
Standard deviation :
Sample size : n= 35
Let x be the random variable that represents the test scores of the students.
The formula for the z-score :-
For x=76
By using the standard normal distribution table ,
The p-value =
Hence, the probability that that the mean of their test scores will be greater than76 =0.5%
Final answer:
The probability that the mean test score of 35 randomly selected Sociology students will be greater than 76 is 0.5%, calculated by using the Central Limit Theorem and the Z-score formula.
Explanation:
In Sociology, to find the probability that the mean of the test scores for a randomly selected group of 35 students will be greater than 76, we use the concepts of the Central Limit Theorem and the Z-score formual.
First, we calculate the standard error which is the standard deviation divided by the square root of the sample size (9.2/sqrt(35) which roughly equals 1.55).
Next, we calculate the Z-score which is the difference between the sample mean and population mean divided by the standard error (76-72)/1.55, which equals roughly 2.58.
Finally, by looking at the Z-table, we find that the area to the left of Z=2.58 is 0.9951, which means that the area to the right (representing the probability of a score >= 76) is 1 - 0.9951= 0.0049 or 0.5%. So the probability that the average test score of the randomly selected 35 students will be greater than 76 is 0.5%.

The solution is, the probability that both cards are red is 5/22.
What is probability?
Probability can be defined as the ratio of the number of favorableoutcomes to the total number of outcomes of an event.
here, we have,
given that,
Gregg has 12 cards.
Half are black, and half are red.
i.e. red = 6 & black = 6.
He picks two cards out of the deck.
now, we have,
Probability of a red card out of 12 cards = 6/12 = 1/2
Now, probability of a red card of 11 cards = 5/11
so, we get,
Combined probability = 1/2 * 5/11 = 5/22
Hence, The solution is, the probability that both cards are red is 5/22.

Now, probability of a red card of 11 cards = 5/11
Combined probability = 1/2 * 5/11 = 5/22
In short, Your Answer would be 5/22
