348 of the 400 randomly sampled graduates fouse degrees. Suppose we conduct a survey and find out that over 4500 students. a) What is the value of the point estimate of this parameter? b) Check if the conditions for constructing a confidence interval based on these data are met. Independence condition Success-failure condition c) Calculate a $$95 \%$$ confidence interval for the proportion of graduates who found a job within one year of completing their undergraduate degree at this university, and interpret it in the context of the data. We are $$95 \%$$ confident that approximately \\$ so fenter the smalter number first, to the nearest tenth of a percent) of graduates from this university found a job within one year of completing their undergraduate degree. e) Now catculate a $$99 \mathrm{k}$$ confidence interval for the same parameter and interpret it in the context of the data. We are $$99 \%$$ confident that approximately o fonter the smaller number first, to the nearest tenth of a percent) of graduates from this university found a job within one year of completing, their undergraduate degree. f) Compare the widths of the $$95 \%$$ 3ls. Which one is wider? Why is this?
