Answer:
2 imaginary roots
Step-by-step explanation:
8.71 xx10^(12)
The exponent is a positive number. This means the decimal point moves to the right by the number of the exponent.
There are two digits to the right of the decimal point, so to move the decimal 12 places, you would need to add 10 zeros.
8.71 x 10^12 becomes 8,710,000,000,000.
Test statistic = (mean 1 - mean 2) / sqrt( dev1/n1 + dev2/n2)
Mean 1 = $16.75
mean2 = $16.25
dev1 = $1.00
dev2 = $0.90
n1 = 80
n2 = 60
Test stat = (16.75 - 16.25) / sqrt(1/80 + 0.95/60)
Test stat = 3.01
The answer is B. 3.01
