What is P(X≥2)P(X≥2)?
Enter your answer in the box.
2.There are 10 cards. Each card has one number between 1 and 10, so that every number from 1 to 10 appears once.
In which distributions does the variable X have a binomial distribution?
Select each correct answer.
When a card is chosen at random without replacement three times, X is the number of times an even number is chosen.
When a card is chosen at random with replacement multiple times, X is the number of times a card is chosen until a 5 is chosen.
When a card is chosen at random with replacement six times, X is the number of times a 3 is chosen.
When a card is chosen at random with replacement five times, X is the number of times a prime number is chosen.
3.Select Yes or No to state whether each data set is likely to be normally distributed.
Yes No
the number of coupons used at a supermarket
the weights of the pumpkins that are delivered to a supermarket
the number of raisins in each 8-oz box of raisins at a supermarket
the amount of time customers spend waiting in the checkout line at a supermarket
4.A machine packages bags of almonds. The weights of the bags are normally distributed with a mean of 14 oz and a standard deviation of 1.2 oz.
Enter the z-score of a bag of almonds that weighs 12.2 oz.
5.The heights of the children at a summer camp are normally distributed with a mean of 54 in. and a standard deviation of 2.4 in.
Enter the height of a child, whose z-score is 1.5, in the box.
Round your answer to the nearest tenth.
6.Use technology or a z-distribution table to find the indicated area.
The scores on a standardized exam are normally distributed with a mean of 400 and a standard deviation of 50.
Approximately 60% of the scores are less than which score?
a.370
b.387
c.413
d.430
7.Use technology or a z-distribution table to find the indicated area.
The weights of boxes of rice produced at a factory are normally distributed with a mean of 24 oz and a standard deviation of 1.3 oz. Consider a shipment of 1200 boxes of rice.
How many of the boxes will weigh 25 oz or less?
a.192
b.265
c.935
d.1008
These are 7 out 30 of the question I have it would be so awesome if someone can help me really fast. Found 2 solutions by advanced_Learner, ewatrrr:Answer by advanced_Learner(501) (Show Source):
You can put this solution on YOUR website! 1. P(x>= 2) = 1-(.03+.09) = .88
4. z = (12.2-14)/1.2
5. x = 1.5(2.4) + 54
6. invNOrm(.60) = .2533, x = .2533(50) + 400 = 413
7. z = (25-24)/1.3 = .77 P(z<= .77) = .779
.779(1200) = 935
