Asked Nov 5, 2019

It is believed that 67.3% of Americans own their own homes. Suppose a sample of 50 Americans were selected.

c) Find the probability that the sample selected has more than 70% of the Americans that are homewoners.

Step 1

Consider,

*X* be random variable that shows the number of people who has their own home which follows binomial distribution. That is,

Step 2

Since, sample size is large enough (n>30) therefore* x* follows normal distribution that is normal approximation of binomial.

Here,* x* represents the sample...
