The world is currently being adversely affected by the COFLU-20 pandemic. Persons are required to take certain measures to prevent the spread of this virus; however, persons' knowledge, attitudes and practices towards COFLU-20 may influence their adherence to these measures. A researcher decided to evaluate the knowledge, attitudes and practices towards COFLU-20 of adults living in the English-speaking Caribbean. To gather the data, the researcher developed an online survey consisting of four (4) sections. Section A gathered demographic data on the respondents including their gender, marital status, highest level of education attained, occupation and country of residence. Section B consisted of 15 questions that gathered data on the respondents' knowledge of COFLU-20. Section C consisted of 10 questions that gathered data on the respondents' attitudes towards COFLU-20. The final section, Section D, consisted of 5 questions that gathered information on the respondents' practices against COFLU-20. In order to recruit respondents for this survey, the researcher sent a link to the online survey to persons in his network via email and social media. After receiving 300 responses, the researcher closed down the online survey and deactivated the link to the survey. You are a student pursuing an introductory Statistics course. The researcher has asked that you assist him in summarizing, analyzing and interpreting the information gathered, by answering the questions below. To examine practices towards COFLU-20, the researcher examined the relevant responses from the survey and assigned scores of 1 (below required 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 sbewn in Table 3 below. Table 3 3 P(X =x) 0.21 0.197 0.2 0.173 0.22 The researcher is interested in using the information in Table 3 to determine the probability that, froma sample of 10 randomly selected adults, exactly 3 of them exceeds the required standard for practices towards COFLU-20.

Question

Individual scores for practices towards COFLU-20 are found to be normally distributed 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 COFLU20 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?

The world is currently being adversely affected by the COFLU-20 pandemic. Persons are required to
take certain measures to prevent the spread of this virus; however, persons' knowledge, attitudes and
practices towards COFLU-20 may influence their adherence to these measures.
A researcher decided to evaluate the knowledge, attitudes and practices towards COFLU-20 of
adults living in the English-speaking Caribbean. To gather the data, the researcher developed an
online survey consisting of four (4) sections. Section A gathered demographic data on the
respondents including their gender, marital status, highest level of education attained, occupation
and country of residence. Section B consisted of 15 questions that gathered data on the respondents'
knowledge of COFLU-20. Section C consisted of 10 questions that gathered data on the
respondents' attitudes towards COFLU-20. The final section, Section D, consisted of 5 questions
that gathered information on the respondents' practices against COFLU-20.
In order to recruit respondents for this survey, the researcher sent a link to the online survey to
persons in his network via email and social media. After receiving 300 responses, the researcher
closed down the online survey and deactivated the link to the survey.
You are a student pursuing an introductory Statistics course. The researcher has asked that you assist
him in summarizing, analyzing and interpreting the information gathered, by answering the
questions below.

To examine practices towards COFLU-20, the researcher examined the relevant responses from the
survey and assigned scores of 1 (below required 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 sbewn in Table
3 below.

The researcher is interested in using the information in Table 3 to determine the probability that, froma
sample of 10 randomly selected adults, exactly 3 of them exceeds the required standard for practices
towards COFLU-20.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
