Conduct a test at the alpha

equals

=0.05

0.05 level of significance by determining (a) the null and alternativehypotheses, (b) the teststatistic, and(c) theP-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 122

x1=122, n 1 equals 244

n1=244, x 2 equals 144

x2=144, and n 2 equals 309

n2=309.

Determine the test statistic?

Round to two decimal places
