Answer:
CI =(0.333, 0.480)
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as shown;
CI = p±Z * √p(1-p)/n±0.5/n
Z is the z-score at 90% confidence
p is the sample proportion
n is the sample size
Given n = 144, p = 0.4 and z-score at 90% CI = 1.645 (from z table)
Substituting this values;
CI = p ± 1.645*√0.4(1-0.4)/144 ±0.5/n
CI = 0.4 ± 1.645*√0.4(0.6)/144 ± 0.5/144
CI = 0.4 ±1.645 * √0.24/144 ± 0.00347
CI = 0.4 ±1.645 * 0.04087± 0.00347
CI = 0.4±0.06723±0.00347
CI =(0.333, 0.480)
Answer:
I think the answer is 3.14
Step-by-step explanation:
Your answers would be -5 , -4
Answer:
a. Weekly Gross pay:
= 9.50 * 20
= $190
b. Federal tax withheld:
= 10% * 190
= $19
c. FICA Tax withheld:
= 5.65% * 190
= $10.74
d. State tax withheld:
= 5% * 190
= $9.50
e. Weekly net pay
= Gross pay - taxes
= 190 - 19 - 10.74 - 9.50
= $150.76
f. Percentage withheld for taxes:
= (19 + 10.74 + 9.50) / 190 * 100%
= 20.7%
I think it’s c but i’m kinda dumb so idk
