Suppose that 29% of undergraduates at a large university are involved in a campus organization. The administration plans to take an SRS of 100 undergraduates from the population of over 20,000 undergraduate
students at the school to see what proportion of students sampled are involved in a campus organization.
What are the mean and standard deviation of the sampling distribution of the proportion of undergraduate
students who are involved in a campus organization?

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
