Question

ten percent of the population is left - handed. a class of 6,550 students is selected. convert the binomial probability ( p(xleq11) ) to a normal probability by using the correction for continuity.

a. ( p(x > 11.5) )
b. ( p(xleq11.5) )
c. ( p(x < 10.5) )
d. ( p(xgeq10.5) )

Explanation:

When converting a binomial probability \(P(x\leq n)\) to a normal probability using the continuity correction, we add \(0.5\) to \(n\). Here \(n = 11\), so we use \(P(x\leq11.5)\).

Answer:

B. \(P(x\leq11.5)\)
