balandron [24]

Answer:

$1.\ \ np\geq 10\\\\2.\ \ n\geq 10x$

-The conditions for a one-sample proportion z-test are:

-The sample is randomly selected from the population.

-The sample size is greater than or equal to ten times the population size:

$n\geq 10x\\\\n=2000\\x=150\\10x=1500\\\therefore n\geq 10x$

-The expectation np is greater than or equal to 10:

$np\geq 10\\n=2000, p=0.6\\np=1200\\\\Hence, np\geq 10$
