The mean of a population being sampled is 64, and and the standard deviation is 6.If the sample size is 50, the standard error of the mean is . (Round off your answer to the nearest hundredth.)

Answers

Answer 1

Answer: Given:
mean of the population being sampled = 64
standard deviation = 6
sample size = 50

standard error of the mean=standard deviation of the original distribution
root of the sample size

standard error of the mean = 6 / √50
standard error of the mean = 6 / 7.07
standard error of the mean = 0.848 or 0.85

Answer 2

Answer:

The mean of a population being sampled is 64, and and the standard deviation is 6.

If the sample size is 50, the standard error of the mean is 0.85. (Round off your answer to the nearest hundredth.)

Ali and Kiana buried a treasure together on their school's field. The actual field is 400 feet wide. Ali made an 8-inch-wide map to record its location. Kiana made her map using a scale of 1 in. To 20 ft. On Kiana's map, the treasure is 2 inches from the south edge of the field. How far is the treasure from the south edge on Ali's map?

Answers

Answer:

The treasure is 0.8 inches from the south edge on Ali's map.

Step-by-step explanation:

Scaling factor, f = (Original length)/(Scalet length)...(i)

Let $f_1$ and $f_2$ be the scaling factors used by Ali and Kiana respectively.

Given that the field is 400 feet= 400x12 inches wide and Ali made an 8-inch-wide map to record its location.

So, $f_1 = (400*12)/8=600$ ...(ii)

Kiana made her map using a scale of 1-inch to 20 feet=20x12 inches.

So, $f_2=(20*12)/1=240$ ...(iii)

As on Kiana's map, the treasure is 2 inches from the south edge of the field,

so, from equations (i), and (ii), the original length of the treasure for the south edge of the field

$=2* f_2$

=2x240

=480 inches

Now, again from the equation (i) and (ii), the scaled length of the treasure on Ali's map

= 480/f_1

=480/600

=0.8 inches

Hence, the treasure is 0.8 inches from the south edge on Ali's map.

Last year, manuel saved $50 per month . this year, he increases his monthly savings by 25%. he plans to buy a smart phone for $375. at this rate, how long will it take him to save enough money to buy the smart phone if he starts saving for it this year?

Answers

First multiply 50 and .25 to find out how much extra he is saving, $12.5 Then add that to 50 to get $62.5. Divide $375 by $62.5 to get 6. It will take 6 months to save the money. Hope this helps!

Answer:

$1644.

Step-by-step explanation:

We have been a typical household in the United States has an average after-tax income of $41,100. We are asked to find how much more is spent on insurance/pensions than on health care.

We have been given that 5% is spent on health care and 9% is spent on insurance/pensions. This means that 4% (9%-5%) is more on insurance/pensions than on health care.

Now, we need to find 4% of $41,100.

$\text{Amount more spent on insurance/pensions than on health care}=(4)/(100)* \$41,100$

$\text{Amount more spent on insurance/pensions than on health care}=4* \$411$

$\text{Amount more spent on insurance/pensions than on health care}=\$1644$

Therefore, $1644 is more spent on insurance/pensions than on health care.
