Answer:
11 hours
Step-by-step explanation:
104 dollars for 8 hours of work. So how much money per hour?
104/8= 13 dollars per hour
At the same rate = 13 dollars per hour, so
How many hours to make 143 dollars? With the same rate?
143/13 = 11 hours
Answer: p = 0.73
Step-by-step explanation:
Given that,
73% of the audience was under 20 years old :
so, probability (p) = 0.73
n = 146
Mean of the distribution of sample proportion = ?
According to central limit theorem,
np(1-p) ≥ 10
146 × 0.73(0.27) ≥ 10
28.77 ≥ 10
∴ Central limit theorem assumes that the sample distribution of the sample proportion is normally distributed.
Hence, the mean of the distribution of sample proportion:
μ = p = 0.73
