Suppose you asked 100 commuters how much they spend each year and obtained a mean of $167 spent on transportation and a standard
Lena [83]

Answer:

The correct answer is "$159 and $175".

Step-by-step explanation:

The give values are:

Mean,

= $167

Standard deviation,

\sigma = $40

Number of commuters,

n = 100

Now,

⇒ SE=\frac{\sigma}{\sqrt{n} }

On putting the given values, we get

⇒       =\frac{40}{\sqrt{100} }

⇒       =\frac{40}{10}

⇒       =4

By using the 2 SE rule of thumb, we get

= $(167 - 2\times 4)

= 167-8

= 159 ($)

Or,

= (167 + 2\times 4)

= 167+8

= 175 ($)

i.e,

$159 and $175
