You see how many times 6 can fit into 13 (two), and see how many 6ths are left (one). So the answer would be 2 and 1/6.
Answer: 321q = z
This is the same as z = 321q
The term "product" means "result of multiplying two or more values"
For example, the product of 2 and 3 is 2*3 = 6
Writing 321q is the same as 321*q, but we often leave out the multiplication sign. You could say q*321, but convention usually has the number come first then the variable second. The 321 is the coefficient.
That is a very good question....
Look Grank
you know that:
confidence interval = mean +or- Margin of Error
and
Margin of Error = (z)*(standard deviation) / (sqrt of n)
where n is the number of sample records
So we need to calculate z-value firstly
It says: "<span>we want 90% confidence"
So that:
</span>
<span>confidence90% corresponds to z-value of 1.645
Plug that into our formula of </span><span>Margin of Error:
</span>Margin of Error = (1.645)*(22) / (sqrt of n)
"The sample mean is within 2.7 lb of the population mean" means that Margin of Error is 2.7
<span>Margin of Error:
</span>2.7 = (1.645)*(22) / (sqrt of n)
Now solve for n:
n=179.66~180
SO that 180<span> women must be randomly selected to estimate the mean weight of women in one age group.</span>
