The description of the given question is described in the explanation section below.

Step-by-step explanation:

Yes, the usual requirement for seeking phases or intervals of trust is fulfilled since np = 18 as well as n (1 - p) = 57, many of which are larger than 10, the standard confidence duration searching requirement is achieved since the sample group or its size reaches 30. Even though the study would be a simple random survey, the usual criterion for identifying confidence intervals is observed.
