Recall the chapter example which described the fact that the mean IQ in large, diverse populations is 100 and the standard devia
vova2212 [387]

Answer:

The margin of error for the 99% confidence level for this sample is ±2.23.

None of the given figures is close to the answer:

E. None of the above

Step-by-step explanation:

margin of error (ME) around the mean can be calculated using the formula

ME=\frac{z*s}{\sqrt{N} } where

  • z is the corresponding statistic of the 99% confidence level (2.576)
  • s is the population IQ standard deviation (15)
  • N is the sample size (300)

Using these numbers we get:

ME=\frac{2.576*15}{\sqrt{300} }  ≈ 2.23

I made 10 and three fifths gallons of soup of which 6 and one quarter gallons was chicken noodle. How much was not chicken noodl
nata0808 [166]

Answer: 4 7/20 gallons

Step-by-step explanation:

Gallons of soup made = 10 3/5

Gallons that was chicken noodle = 6 1/4

The gallons that wasn't chicken noodle will be:

= 10 3/5 - 6 1/4

= 10 12/20 - 6 5/20

= 4 7/20

Therefore, 4 7/20 gallons wasn't chicken noodle.
