A teacher would like to estimate the mean number of steps students take during the school day. To do so, she selects a random sa

mple of 50 students and gives each one a pedometer at the beginning of the school day. They wear the pedometers all day and then return them to her at the end of the school day. From this, she computes the 98% confidence interval for the true mean number of steps students take during the school day to be 8,500 to 10,200. If the teacher had used a 90% confidence interval rather than a 98% confidence interval, what would happen to the width of the interval?
It would increase by 8%.
It would decrease by 8%.
It would increase, but not necessarily by 8%.
It would decrease, but not necessarily by 8%.

What is the GRM for a residential duplex with a selling price of $234,000 if the monthly rent for each unit is $925? A. l.054 B.
stiks02 [169]

Answer:

126.5

Step-by-step explanation:

Given :The monthly rent for each unit is $925

To Find : What is the GRM for a residential duplex with a selling price of $234,000 if the monthly rent for each unit is $925?

Solution:

Annual Gross Rents = $925

Property Value = $234,000

For answer to be 126.5 , $925 must be semiannual rent

So, annual rent = 925*2

Formula : Property Value = Annual Gross Rents X Gross Rent Multiplier (GRM)

Substitute the values :

234000=925 \times \text{Gross Rent Multiplier}

\frac{234000}{925 \times 2}= \text{Gross Rent Multiplier}

126.5 = \text{Gross Rent Multiplier}

Hence The GRM for a residential duplex with a selling price of $234,000 if the monthly rent for each unit is $925 is  126.5

So, Option D is true .
