Asurvey shows that 45% of the respondents pick option a. given that 50 people replied, what is the standard error of the proportion

0.07

Step-by-step explanation:

Given: A survey shows that 45% of the respondents pick option

i.e. P =45%= 0.45

Q=1-P=1-0.45=0.55

The total number of people replied n = 50

Now, the standard error of the proportion is given by :-

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
