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

A $900 notebook computer is discounted 5% what is the sale price of a notebook computer

fenix001 [56]

The sale price of computer is $855

Step-by-step explanation:

First of all the discount is calculated and then subtracted from the original price to calculate the sale price

Given

price of notebook computer = $900

Discount = 5%

So,

$Discount = 5\%\ of\ 900\\= 0.05 * 900\\= \$45$

Now,

$Sale\ price = Original\ price - Discount\\= 900-45\\=855$

Hence,

The sale price of computer is $855
