Answer:
(0.392 ; 0.508)
Step-by-step explanation:
Given that :
p = 45% = 0.45
α = 1 - 90% = 0.1
Zα/2 = Z0.01/2 = Z0.05 = 1.645 (from Z standard table).
Using the relation :
p ± Z0.05*sqrt((p(1-p))/n)
p ± 1.645 * sqrt(0.45(0.55)/200)
p ± 1.645 * sqrt(0.0012375)
p ± 1.645 *0.0351781
0.45 - (1.645 * 0.0351781) = 0.3921320255
0.45 + (1.645 * 0.0351781) = 0.5078679745
(0.392 ; 0.508)
Answer:
109
Step-by-step explanation:
Answer:
Step-by-step explanation:
58.6% of the total income is 17,000
let x represent the total income
58.6%(x) = 17,000...turn ur percent to a decimal
0.586x = 17,000
x = 17,000 / 0.586
x = 29010.238 rounds to 29,010.24 <== total yearly income
check...
58.6% of 29,010.24 = 17,000
0.586(29,010.24) = 17,000
17,000 = 17,000 (correct)
