Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The margin of error is 
The standard deviation is 
From the question we are told the confidence level is 94% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%20%2A%20%20%5Csigma%20%7D%7BE%7D%20%5D%20%5E2)
=> ![n = [\frac{1.881 } * 22 }{5} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B1.881%20%7D%20%2A%20%2022%20%7D%7B5%7D%20%5D%20%5E2)
=>

Answer:
Step-by-step explanation:
Step-by-step explanation:
to round 4.645 to the nearest whole number consider the tenths’ value of 4.645, which is 6 and equal or more than 5. Therefore, we have to round up: the whole number part of 4.645, 4, increases by 1 to 5, and the decimal point and all digits (.645) are removed.
4.645 rounded to the nearest whole number = 5
