Answer:
e^6 ≈ 403
Step-by-step explanation:
You want the value of e^(4x-2) when x = 2.
<h3>Evaluation</h3>Put 2 where x is in the expression and do the arithmetic.
e^(4·2 -2) = e^6 ≈ 403.429
The value of the expression is about 403.
Answer:
The 90% confidence interval of the population proportion is (0.43, 0.56).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population proportion <em>p</em> is:
The information provided is:
<em>X</em> = 74
<em>n</em> = 150
Confidence level = 90%
Compute the value of sample proportion as follows:
Compute the critical value of <em>z</em> for 90% confidence level as follows:
*Use a <em>z</em>-table.
Compute the 90% confidence interval of the population proportion as follows:
Thus, the 90% confidence interval of the population proportion is (0.43, 0.56).
