Answer:

The sample size will be "102.5494 \sim 102". A further explanation is given below.

Step-by-step explanation:

Let the sample size will be:

= n

The given values are:

Standard deviation,

= 1.4

ME,

= 0.3

As we know,

⇒ n=(Z \frac{a}{2}\times \frac{SD}{E})^2

On putting the estimated values, we get

⇒    =(2.17\times \frac{1.4}{0 .3})^2

quester [9]

<span>If you would like to know how many of each did Jan buy, you can calculate this using the following two equations:

b ... the number of books
m ... the number of magazines

$16 = b * $3 + m * $2.50 ... 16 = 3 * b + 2.50 * m
b + m = 6 ... b = 6 - m
__________________
</span>16 = 3 * b + 2.50 * m

<span>16 = 3 * (6 - m) + 2.50 * m</span>

16 = 3 * 6 - 3 * m + 2.50 * m

16 - 18 = - 3 * m + 2.50 * m

- 2 = - 0.50 * m     /0.50

m = 2 / 0.50

m = 4 magazines 

<span>b = 6 - m = 6 - 4 = 2 books</span>

Result: Jan bought 4 magazines and 2 books.
