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!!!
