Answer:
-t
Step-by-step explanation:
Additive inverse of t:
t*-1 = -t
Answer:
0.078
Step-by-step explanation:
Margin of error = z√(p(1-p)/n)
Given
p-hat = 0.43
n = 270
z at 99% confidence interval = 2.576
Substitute
MOE = 2.576√0.43(1-0.43)/270
MOE = 2.576√0.43*0.57/270
MOE = 2.576√0.2451/270
MOE = 2.576*0.030129
MOE = 0.078
Hence the margin og error is 0.078
78 to 338
Adults to children
78:338
78 over 338
Probability is 0/12 since there are no blue lollipops in the bag.
