Answer:

Step-by-step explanation:

p = .3

n = 150

p(bar ) = 1 - p = .7

$\sigma_p=\sqrt\frac{p(1-p) }{n} }$

$\sigma_p=\sqrt\frac{.3(1-.3) }{150} }$

=.037

b )

P ( .2 <p<.4 ) = P [ (.2 - .3) / .037 < z < ( .4 - .3 ) / .037 ]

= P [ (-2.7 < z < +2.7 ]

= .9965-.0035

= .993

c )

P ( .25 <p<.35 ) = P [ (.25 - .3) / .037 < z < ( .35 - .3 ) / .037 ]

= P [ (-1.35 < z < +1.35 ]

= .9115 - .0885

= .823
