12. (A) Figure 3 presents vitamin D (vitD) intake of women in the Cape Coast Metropolis during the period of pregnancy. a. What is the sample size for the study? b. Estimate mean vitD intake of the sample c. Indicate the modal class d. Is the mean computed a representative measure of the average vitD intake of the sample? Explain e. What is the proportion of women with vitD intake between 200 and 400 ug/day f. What is the shape of the distribution? g. How does the three measures of central location compare in this distribution? h. Indicate the exact type and scale of measurement of vitD intake i. The standard deviation for the sample is 96.86 ug/day. Compute the standard error and indicate what it signifies 400 300 Frequency 200 100 0 4 (63 200 400 600 800 vitd Figure 3
