- A survey of 90 recently delivered women on the rolls of a county welfare department revealed that 27 had a history of intrapartum or postpartum infection. What is the critical value of z if we need to conclude that the population proportion with a history of intrapartum or postpartum infection is less than 0.25.Calculate the time for 10 per cent of the sites on a (100) tungsten surface with a bec unit cell and a lattice constant of 316 pm to be covered with nitrogen at 298K when the pressure is 2 x 10 mmHg and the sticking probability is 0.55There are 5000 observations in a data set. 10% of the data are “1”s, while the rest are “0”s. If we oversample “1”s to 50%, how many data points will be excluded from the analysis? Assume that the original percentages of “1” and “0” are restored in the validation data. Show all calculations.
