The number of square feet per house are normally distributed with a population standard deviation of 137 square feet and an unkn

pshichka [43]

Answer:

Step-by-step explanation:

Given that X, the number of square feet per house is N(mean, 137)

Sample size = 19

Sample mean x bar =1350 sq ft

Since population std dev is given,

std error of sample = $\frac{137}{\sqrt{19} } \\=31.43$

Since sample size is small, t critical value can be used

df = 18

t value for 80% two tailed = 1.333

Margin of error = ±1.333(std error) = ± $1.333*31.43\\=41.896$

Confidence interval = sample mean ±margin of error

= $1350-41.896,1350+41.896\\=(1308.104,1391.896)$

Henry wants to buy a new table saw for his carpentry shop. He has saved $360 which is 2/3 of the price of the saw. How much does

Tema [17]

If 360 is 2/3 of the full price on a saw then your equation should look like this:

$360=\frac{2}{3} *x$

x is your unknown full price of the saw. Just solve for x now.

$360=\frac{2}{3} *x\\ \\ x=\frac{3}{2} *360=540$

This means that the full price is $540.

Hope this helps!
