Test the claim by using a sample data obtained from a survey of 600 students of the school while 45% indicated their dissatisfaction of the community canteen service. Use α=0.05. a. The null hypothesis is p≤0.40 p>0.40 p<0.40 p=0.40 b. The alternative hypothesis is p=0.40 p<0.40 p≠0.40

p=0.40
b. The alternative hypothesis is
p=0.40
p<0.40
p≠0.40
p>0.40
c. The value of the test statistic is
2.46
-2.46
2.48
-2.48
d. The p-value is
0.0078
0.0039
0.5000
none of these
e. The Decision is
