Suppose a research firm conducted a survey to determine the average amount of money steady smokers spend on cigarettes during a

olchik [2.2K]

Answer:

option (b) 0.0228

Step-by-step explanation:

Data provided in the question:

Sample size, n = 100

Sample mean, μ = $20

Standard deviation, s = $5

Confidence interval = between $19 and $21

Now,

Confidence interval = μ ± $z\frac{s}{\sqrt n}$

thus,

Upper limit of the Confidence interval = μ + $z\frac{s}{\sqrt n}$

$21 = $20 + $z\frac{5}{\sqrt{100}}$

z = 2

Now,

P(z = 2) = 0.02275 [From standard z vs p value table]

P(z = 2) ≈ 0.0228

Hence,

the correct answer is option (b) 0.0228
