levacccp [35]

Answer:

Mean: 49

Mode: none, since all the numbers only appear once

Median: 48

Range: 69

53+64+19+25+88+48+46 = 343

343/7= 49 (mean)

19, 25, 26, 48, 53, 64, 88 (middle number is 48, so the median is 48)

Range= largest number-smallest number

88-19= 69 (range)

You are researching the average emails received per day. You want to know how many employees you should survey if you want to kn

IrinaK [193]

Answer:

The value is $n =29 \ employees$

Step-by-step explanation:

Generally the number of employee to survey(sample size) is mathematically represented as

$n = [ \frac{z * \sigma }{E} ]^2$

Here E is the margin of error which is given as E = 47

So substituting 1.645 for z and 155 for $\sigma$

$n = [ \frac{1.645 * 155 }{47} ]^2$

=> $n =29 \ employees$
