Step-by-step explanation:
Given that a study of 138 penalty shots in World Cup Finals games between 1982 and 1994 found that the goalkeeper correctly guessed the direction of the kick only 41% of the time.
Set up hypotheses as:

(left tailed test at 5% significance level)
Standard error = 0.043
Sample proportion p = 0.41
p difference = 
Test statistic Z = p diff/std error
= 
Z = -2.09
Answer:
it looks great! i'd give you an a+
honestly I couldn't make that
5t=v-u (Subtract u on both sides)
t=(v-u)/5 (Divide by 5 in both sides)
