Answer:
Given hypothesis are
H0: A = 0.24
H1: Â ≠ 0.24
Here sample proportion  is used to express hypothesis instead of population proportion p.
The error is sample parameter  used in hypothesis [ It should be population parameter p or π )
Step-by-step explanation:
It’s already a fraction so it cannot be simplified anymore
Answer:
4
Step-by-step explanation:
16^1/2 = sqrt(16) = 4
4*4 = 16
Answer:
0.12
Step-by-step explanation:
Independent events are when probability of one event happening doesn't affect the probability of the other event happening.
Also,
In probability "AND" means "multiplication" and "OR" means "addition".
The question asks for probability that Nick oversleeps "AND" has pop quiz. So we need to multiply the individual probabilities (since independent, they have no affect on each other).
P(Nick oversleeps) = 0.48
P(pop quiz) = 0.25
Thus,
P(Nick oversleeps AND pop quiz) = 0.48 * 0.25 = 0.12
