Let x_bar 10,000 be the fraction of heads in 10,000 tosses.
use chebyshev's inequality to bound p(|x_bar - 0.5|> or = .01) and the normal approximation to estimate this probability.
the answers in the book are that the chebyshev's inequality is bounded by 1/4 and the normal approximation is .0455

For the function, f(x) = -5x 2, find f(-4).

Yuto and hila attempted to solve the same inequality. their work is shown below. which statement is true about the work shown above? yuto is correct because he isolated the variable correctly and reversed the inequality symbol. yuto is incorrect because he should not have reversed the inequality symbol. hila is correct because she isolated the variable correctly and reversed the inequality symbol. hila is incorrect because she should not have reversed the inequality symbol.
