Answer #1

1)

Ho : p = 0.5

H1 : p > 0.5

Sample Size, n = 677

Sample Proportion , p̂ = 0.5600

Standard Error , SE = √( p(1-p)/n ) =
0.0192

Z Test Statistic = ( p̂-p)/SE = ( 0.5600
- 0.5 ) / 0.0192
**= 3.12 (answer)**

**---------------**

Standard Error , SE = s/√n = 10.6000 / √
149 =
0.8684**
t-test statistic=** (x̅ - µ )/SE = (
68.700 - 69 ) /
0.8684 =
