Answer:
the probability of observing 27 or more students 0.818
Step-by-step explanation:
given data
sample n = 28 students
population = 93%
to find out
the probability of observing 27 or more students
solution
we will find Z value for CI 93%
from z table we get Z is 1.812 for Cl 93%
so P(27 ≤ Z ≤ 28)
we know Z = 0.182
= 1 - 0.182
= 0.818
the probability of observing 27 or more students 0.818
Answer:
