Answer:
1) null: π = 0.5, alternative: π > 0.5
2)p^= 80/124 =0.645
std error =(phat(1-phat)/n)1/2 =0.0430
3)z = (phat-p)/std erro =(0.645-0.5)/0.0430 =3.22
4)The observed proportion of couples who leaned to the right when kissing is 3.22 standard deviations above the null hypothesized value of 0.50
5)We have strong evidence that the proportion of couples that lean their heads to the right while kissing is more than 50%
