In a study of hormone supplementation to enable oocyte retrieval for assisted reproduction, a team of researchers administered two hormones in different timing strategies to two randomly selected groups of women aged 36-40 years. for the group a treatment strategy, the researchers included both hormones from day 1. the mean number of oocytes retrieved from the 98 participants in group a was 9.7 with a 98% confidence level z-interval of (8.1, 1 1.3) select the correct interpretation of the confidence interval with respect to the study 0 the researchers expect that 98% of all similarly constructed intervals will contain the true mean number of oocytes that could be retrieved from the population of women aged 36-40 years the researchers expect that 98% of all similarly constructed intervals will contain the mean number of oocytes retrieved in the sample of 98 women aged 36-40 years 0 the researchers expect that the interval will contain 98% of the range of the number of oocytes retrieved in the sample of 98 women aged 36-40 years there is a 98% chance that the the true mean number of oocytes that could be retrieved from the population of women aged 36-40 years is uniquely contained in the reported interval. the researchers expect that 98% of all similarly constructed intervals will contain the range of the number of oocytes that could be retrieved from the population of women aged 36-40 years
