Transcribed Image Text:To examine practices towards COFLU-20, the researcher examined the relevant responses from
the survey and assigned scores of 1 (below sequired standard), 2 (poor standards), 3 (satisfactory
standards), 4 (meets required standards) and 5 (exceeds required standard) to each respondent.
Using X to represent the score for practices against COFLU-20, the probability distribution of X
is shown in Table 3 below.

Transcribed Image Text:The researcher is interested in using the information in Table 3 to determine the probability that,
from a sample of 10 randomly selected adults, exactly 3 of them exceeds the required
standard for practices towards COFLU-20.
(2) Assist the researcher by:
) carefully defining the random variable of interest
i) identifying a suitable probability distribution to be used to find the probability that exactly
three (3) adults, out of 10, exceeds the required standard for practices towards COFLU-20.
State the value(s) of the parameter(s) for this distrībution.
i) justifring the suitability of the probability distaībution identified in part (üi)
(rv) caleulating the probability that exactly 3 adults, out of 10, exceeds the required standard
for practices against COFLU-20
(b) Individual scores for practices towards COFLU-20 are found to be normally distaibuted with
a mean of 3 and a standard deviation of 1.5 over the entire population. The Ministry of Health
wishes to use this information to identify individuals whose score on practices towards COFLU-
20 is in the lower 75%, in order to give them relevant information on the best practices towards
COFLU-20. You are asked to assist in calculating the score that the Ministry of Health should
use to decide whether an individual should be given the relevant information?
