Find the value of the test statistic z using z = p ^ - p pq n
a claim is made that the proportion of children who play sports is less than 0.5, and the sample statistics include n = 1320 subjects with 30% saying that they play a sport.

The value of the test statistic is z= -14.53

Step-by-step explanation:

Pcap= 0.3 ,p=0.5 ,q= 1-0.5= 0.5, n=1320

Z= (pcap- p) / √(p×q)/n

Z=( 0.3- 0.5) / √ (0.5 × 0.5)/1320

Z= -0.2/(√0.0001894)

Z= -14.53
