c. Illustrate the distribution in activity b through diagram.

Evelynn challenged Ahri and Kai'Sa to play a series of matches of darts. (with Akali eating her ramen and Seraphine being excited).

Here are the probabilities of each woman winning:

Kai'Sa: 50%; Evelynn: 30%; Ahri: 20%

If they play 6 games, Seraphine calculated that the probability of Ahri will win 1 game, Evelynn will win 2 games, and Kai'Sa will win 3 games is around Blank 1. (The probability is in decimal format with 4 decimal places.)

Akali is thoroughly impressed with Seraphine's arithmetic capabilities and decides to cook her some ramen as well

The average number of pages in a novel is 326 with a standard deviation of 24

pages. If a sample of 50 novels is randomly chosen, what is the probability that

the average number of pages in these books is between 319 and 331?

Create a group with 8 members or ask any 8 people near by. Inquire a specific question that a possible answer is a number. Record those answers of each member of the group or the people you have surveyed. solve for the sample statistic using the computations that we have discussed.

You may also choose from any of the following topics for survey.

• The number of Philippine festivals you have attended
• The number of historical places you have visited
• The number of filipino heroes you have known

solve for the mean, variance, and standard deviation of the given set of data of a population.

A LED company claims that the average life of the LED light bulbs it

manufactures is 1, 500 hours with a standard deviation of 500 hours. If a random sample of 40 bulbs is chosen, what is the probability that the sample mean will be:

A population consists of the five measurements 2, 6, 8, 0, and 1.
