The Dunkin family budgets 6 1/2% of their annual net income of $39,000 for clothes. How much annually do they budget for clothes
ioda
They budget $2,535 annually.

You need to find 6.5% of 39,000 by converting 6.5% to a decimal by moving 2 places to the left, hence .065. Afterwards since you have an annual budget you multiply .065 by 39,000.

The Aluminum Association reports that the average American uses 56.8 pounds of aluminum in a year. A random sample of 51 househo
Vilka [71]

Answer:

0.007

Step-by-step explanation:

We were told in the above question that a random sample of 51 households is monitored for one year to determine aluminum usage

Step 1

We would have to find the sample standard deviation.

We use the formula = σ/√n

σ = 12.2 pounds

n = number of house holds = 51

= 12.2/√51

Sample Standard deviation = 1.7083417025.

Step 2

We find the z score for when the sample mean is more than 61

z-score formula is z = (x-μ)/σ

where:

x = raw score = 61 pounds

μ = the population mean = 56.8 pounds

σ = the sample standard deviation = 1.7083417025

z = (x-μ)/σ

z = (61 - 56.8)/ 1.7083417025

z = 2.45852

Finding the Probability using the z score table

P(z = 2.45852) = 0.99302

P(x>61) = 1 - P(z = 2.45852) = 0.0069755

≈ 0.007

Therefore,the probability that the sample mean will be more than 61 pounds is 0.007
