Looking for help with only B and C, can't for the life of me get the right calculations. could someone give me a step by step and or how to use statcrunch or excel to calculate the test statistic?
Conduct a test at the alpha α equals =0.10 level of significance by determining ?(a) the null and alternative? hypotheses, ?(b) the test?statistic, and? (c) the? P-value. Assume the samples were obtained independently from a large population using simple random sampling.
Test whether p 1 greater than p 2
p1>p2. The sample data are x 1 equals 126
x1=126?, n 1 equals 242
n1=242?, x 2 equals 131
x2=131?, and n 2 equals 303
n2=303.
