Im stuck on these question. Can someone please help:(

Which of the following statements is correct when estimating the difference between two population proportions p1 - pg? 0 The sampling distribution of the difference between the two sample proportions is approximately normally distributed when R1131 2 5 , 112112 2 5 , 111g; 2 5 , 11.ng Z_> 5. The sampling distribution of the difference between the two sample proportions is approximately normally distributed when In 23 30 and mg I: 30 . 0 We must have a sample of matched pairs of observations. 0 The sample sizes must be the same. \fIn a chi-square test of goodness of t based on a multinomial experiment involving k = 5 possible outcomes and n = 150 trials. the null hypothesis to be tested is H0: 131 20.1,p2 202,119,203, 11420.2, pr, 20.2 and the observed frequencies are 12, 32. 42, 36 and 28. Using a: = 0.05, the critical value is: O 1.15. O 0311. O 11.1. Q) 9.49
