Answer:

Answer:

D. +3.82

Step-by-step explanation:

The computation of the test static for this test is shown below:

Data provided in the question

\bar x= $8,745

\mu = $8,500

\sigma = $1,200 and n = 350

Now based on the above information, the test static for this test is

z = (\bar x - \mu)/((\sigma)/(√(n) ) )

z = (\$8,745 - \$8,500)/((\$1,200)/(√(350) ) ) \n

= 3.82

= +3.82

Hence, the test static for this test is +3.82

We simply applied the above formula so that the correct value could come

Ancient Egyptians did not write the fraction 4/5 as 4/5. Instead they used unit fractions. The numerator of a unit fraction is always 1.No denominator used to represent a given fraction can be repeated. For this reason, Egyptians would have written 4/5 as 1/2 + 1/5 + 1/10 and not as 1/2 + 1/10 + 1/10 + 1/10. Write each of the following as a sum of unit fractions.
