In order to find the mean, you first count how many numbers are there. Then, you add all numbers together and divide them by the total of numbers. In this case, you would add (1+2+1+0+3+4+0+1+1+1+2+2+3+2+3+2+1+4+0+0+2+2+1+1+1), which equals to 40. The total of numbers is 25. You divide 40 by 25, and it would get you 1.6. Therefore, your mean is 1.6.
To calculate the median, you list the numbers from least to greatest, and find the middle number. The list for this survey would be 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 4, 4. The middle number of this list is 1, therefore, your median is 1.
The mode is simply the number that appears the most in this list. There are 4 zeroes, 9 ones, 7 twos, 3 threes, and 2 fours. The most in this list would be 1, because there are 9 of them. Your mode is 1.
Mean - 1.6
Median - 1
Mode - 1

What is the probability that a student with a GPA below 3.0 does not enjoy school?
Only 15/60 below 3.0 enjoy school.
Rounded, that equals 25%.
Therefore, there is a 75% probability that a student with a GPA below 3.0 does not enjoy school.

Answer:
The probability that both tests detect the bacteria is 83.66% ....
Step-by-step explanation:
First test has a probability of giving accurate results = 94% = 0.94
Second test has a probability of giving accurate results = 89% = 0.89
The probability that both tests detect the bacteria is:
Multiply both the probabilities:
=0.94*0.89
= 0.8366
Converting the value into percentage, we get
0.8366*100
= 83.66%
Thus the probability that both tests detect the bacteria is 83.66% ....
