balandron [24]

Answer:

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

Step-by-step explanation:

-Let x be the sample size and n the population size

-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

Find the exponential function that satisfies the given conditions:
Nady [450]

Answer:

f(t) = 66·0.995^t

Step-by-step explanation:

You can try t=0 and t=1 in each of the formulas to see which one gives values of 66 and 0.5% less than 66, or 65.67.

The first function has an initial value of 0.5, so is not correct.

The second function gives f(1) = 99, so is not correct.

The third function gives f(1) = 65.67, so is correct.

The fourth function gives f(1) = 66.33, so is not correct.

_____

You can realize that the multiplier will be 0.5% less than 100%, so will be 99.5% = 0.995. This number shows up only in the third selection.
