values falls within. According to El-Masri, M. (2012), CI is one of the most dependable

indicators of accurateness of our assumption. In week five, I gave the data for 10 nurses heights

which was as follows: 60”, 68”, 66”, 65”, 65”. 67”, 63”, 65”, 68”, and 61”. I chose a

convenience sample as I chose from 10 nurses in my workplace. It was quantitative continuous

as it has numbers and may involve fractions. Some faults of this are that it does not represent

the entire population. My choices were made based on ease of recruitment. This method can
