Q20

Answer:
The statement provided is True.
Step-by-step explanation:
The exponential function representing growth is given as follows:

Here,
<em>y</em> = final value
<em>y</em>₀ = initial value
<em>k</em> = growth rate
<em>t</em> = time passed
As the function
is increasing, then the exponential function representing growth is also increasing.
Thus, the statement provided is True.
Answer:
The significance level for this case would be
and the critical value for this case would be:

The margin of error is given by:

And replacing we got:

And the margin of error for this case would be 
Step-by-step explanation:
For this case we have the following dataset given:
represent the sample size
represent the estimated proportion of interest
represent the confidence level
The significance level for this case would be
and the critical value for this case would be:

The margin of error is given by:

And replacing we got:

And the margin of error for this case would be
