Answer:
m=1
Step-by-step explanation:
Yes, and it would be 378,972
Explanation:
Answer:
0.06
Step-by-step explanation:
we can get the answer
30 x 0.2 = 6.0
6/100 = 0.06
80 is the total number of students
Total cost: $10/student x 80 = $800
$960 x 2 = $1,920
In order to get the total cost per student, we need to get the sum of the cost of the food and bus rental. So 800 + 1,920 would be $2,720.
Now, divide the sum by 80 (number of students) and the result is 34. So the total cost per student is $34.
Answer:
b) Dependent sample
Step-by-step explanation:
Given:
Sample size, n = 1400
The average sleep of the respondents in weekdays = 6.5 hours
The average sleep of the respondents in weekends = 7.2 hours
% with eight or more hours of sleep on weekdays = 20%
% with eight or more hours of sleep on weekends = 43%
Required: To Check if the samples on weekdays and weekends are independent or dependent.
When samples are independent, it means one sample does not influence the other and vice versa, while samples are said to be dependent if the outcome of one test influences the outcome of the other. The tests might be from a similar population or from various populations.
In this case, the sample gathered are from similar population because same sample is used for both weekdays and weekends. Therefore, we can say the sample is a paired sample.
The samples on weekdays and weekends are dependent since same people are used, also since sleep on weekdays and sleep on weekends may influence each other.
