Answer:

Test statistic = 2.8965

Step-by-step explanation:

The test statistic is given by the formula

z = (x - μ)/σₓ

μ = mean = 0.799

x = proportion of literate people in Tamil Nadu = (983/1185) = 0.8295

σₓ = standard error of this calculated proportion = √[p(1-p)/n]

= √(0.8295 × 0.1705/1185) = 0.01093

z = (x - μ)/σₓ

z = (0.8295 - 0.799)/0.01093 = 2.8965

z = 2.8965

Hope this Helps!!!

Answer:

The Asymptote would be at -3

Step-by-step explanation:

Just remember, when the number at the bottom (not the x) is positive, the graph would shift left by that number. And if it is negative, the graph would translate right by that number.

Since the function has positive 3, the asymptote is at -3

If the function was -3, the asymptote is at 3

EXTRA STUFF: If there is a number next to the fraction, that is not part of the denominator, then that is where the horizontal asymptote would be.
