Question 6_ 1 p "How long in a week do you visit the gym for exercise? Please encircle your answer." What type of question is provided above? Open ended question Close-ended question Anything goes question O Observed questionQuestion 5 1 pts In order to determine the standard heights and weights of Filipinos 0-19 years of age. the food and Nutrition Research Institute (FNRI) conducted an anthropometric survey. To assure the representativeness of the sample. subjects were taken from each of the thirteen regions of the country. From each region, two sample provinces were drawn. From each of the sample provinces, two municipalities were drawn; in turn. two barangays from each municipality were selected. Within each sample barangay. sample households were chosen by systematic sampling. All apparently "healthy' individuals 019 years of age in each sample household were included in the study ( Dr, Mendoza et al. Foundations of Statistical Analysis for the Health Sciences, p60) What sampling design was used? O 5 Stages Stratined Random Cluster Sampling O/3 Stages Stratified Random Cluster Sampling 6 Stages Stratified Random Cluster Sampling 4 Stapes Stratibed Random Cluster SamplingQuestion 8 1 pts Problem B In 2019. investigators from Brown University would like to determine the relationship of nail polish remover and ovarian cancer In women. A cohort of n- 1000 beauticians aged 18-61 years old was identified and followed up after five years. After the follow up period. there were x - 20 new cases of breast cancer were diagnosed. It is known that the incidence of ovarian cancer over the time period for average American women is 7/1000. The researchers wish to determine if the incidence computed in this study is equal to the incidence known in America at 0.01 level of significance. Hypothesis testing for one proportion is possible since the computed nP and nQ values are as ., and respectively, which are - 5. 0.02. 5007 O 953. / 0 7. 993 0 0.007. 0.02Question 9 Problem B In 2019, investigators from Brown University would like to determine the relationship of nail polish remover and ovarian cancer in women. A cohort of n=1000 beauticians aged 18 64 years old was identified and followed up after five years. After the follow-up period. there were x - 20 new cases of breast cancer were diagnosed. It is known that the incidence of ovarian cancer over the tune penod for average American women is 7/1000. The researchers wish to determine if the incidence computed in this Study is equal to the incidence known in America at 0.01 level of significance. Since the computed test statistic value of IS the critical region, we __the null hypothesis 0 394, within reject O 4.93. not within. do not reject 0 493. within. reject () 3.94. not within, do not reject
