Suppose 16% of the listeners of a radio station listen to it while they are at work. what is the approximate standard deviation of the sampling distribution of the proportion for the sample of size 72

Answer with explanation:

Sample Size (n)=72

→P=% of people who listen to radio while they are at work =16 %

→B=1 - P= 100% - 16% =84%

→Standard Deviation when Probability and Sample Size is given

So, standard deviation of the sampling distribution of the proportion for the sample of size 72= 0.0432=0.043 (Approx)

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
