In Mr. Huanabe’s class, students are split into groups of 8. Each group member measured the length of his or her hair. Veronica
had the longest hair in her group, with a length of 42 inches. The other seven group members had hair lengths measuring 13, 23, 24, 5, 5, 13, and 8 inches. Find the mean, median and mode without and with Veronica’s hair length, and explain the changes.

Answer:
0.01596
Step-by-step explanation:
A scientist claims that 8% of the viruses are airborne
Given that:
The population proportion p = 8%
The sample size = 477
We can calculate the standard deviation of the population proportion by using the formula:
The required probability can be calculated as:
= P(Z < -2.41) + P(Z > 2.41)
= P(Z < -2.41) + P(Z < -2.41)
= 2P( Z< - 2.41)
From the Z-tables;
= 2 ( 0.00798
= 0.01596
Thus, the required probability = 0.01596
