Answer:
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
Step-by-step explanation:
Probability of a defective part:
0.04 of 
, that is, coming from A.
0.05 of 
, that is, coming from B. So
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
Answer:
His salary is $2666.68
Step-by-step explanation:
First add the percent of the costs. 10% + 15% = 25%
Then subtract 25% from 100% to find the percentage that 2,000 is of the total salary. 100% - 25% = 75%
$2,000 is 75% of the total salary. Divide 2,000 by three to find the amount of money 25% of the salary is. ( 75% is 3/4 of 100) 2,000 divided by 3 = $666.67
25% of the salary is $666.67
Multiple that by 4 and you get the total salary.
666.67•4= $2666.68
Are you sure those were all the correct numbers because that was not a very nice number at the end there lol but that answer is correct with the numbers you gave me.
Answer:
Standard error = 0.070
Step-by-step explanation:
Formula for the standard error of the distribution of differences in sample proportions is;
σ_(A - B) = √((p_a^(1 - p_a^)/n_a) + (p_b^(1 - p_b^)/n_b))
We are given;
p_a^ = 0.48
n_a = 80
p_b^ = 0.13
n_b = 66
Thus;
σ_(A - B) = √((0.48(1 - 0.48)/80) + (0.14(1 - 0.13)/66))
σ_(A - B) = √0.00496545455
σ_(A - B) = 0.070
