Answer: 3 classes
If we removed 5 students from each of the classrooms, we would be able to keep the 18 classes and give them exactly 30 students. However, we would also have the leftover students to put into classrooms.
If there are 18 classrooms with 5 extra students from each, we can use 18*5 to find how many total students we have.
18 * 5 = 90.
If each class size is 30, we need to divide 90 by 30 to find how many classes we need.
90 / 30 = 3 classes
Answer:
p value =0.544
Step-by-step explanation:
Given that in a survey, 33% of the respondents stated that they talk to their pets on the telephone.
(left tailed test at 1% level)
Sample proportion p =
Assuming H0 to be true, std error of proportion
=
p difference = -0.0233
Test statistic Z = p difference/std error
= -0.6067
p value = 0.544
Since p > alpha, we accept H0
1 1/4 - 1/4 = 1..............
