Answer: 95% confidence interval would be (0.344,0.456).
Step-by-step explanation:
Since we have given that
n = 295
x = 118
so, 
At 95% confidence, z = 1.96
So, margin of error would be

so, 95% confidence interval would be

Hence, 95% confidence interval would be (0.344,0.456).

Answer:
raise = $0.76
new wage = $10.26 per hour
Step-by-step explanation:
8% in decimal form = 8/100 = 0.08
To find 8% of 9.50: 0.08 x 9.50 = 0.76
Therefore, the housekeeper's raise = $0.76
To calculate the amount she now earns after the raise, add the 8% rise to the initial value:
0.76 + 9.50 = $10.26
