Day 1 2 3 4 5 6 7 8 9 10

# of Fish 9 24 8 9 5 8 9 10 8 10

A. Find the mean, median, and mode

B. Find the range, variance, and sample standard deviation

2) A multiple-choice test consists of 20 questions. A student has to answer at least 9 questions correctly to pass the test. Use BINOMIAL DISTRIBUTION to find the probability that a student at random will pass the test?

Expert Solution

1. A) Mean, Median, Mode;

b) Range = Maximum value - Minimum value = 24 - 5 = 19

2) If each question has 2 options then p = 1/2=0.5, n = 20

The probability that a student at random will pass the test is

If each question has 4 options then p = 1/4=0.25, n = 20

The probability that a student at random will pass the test is
