Answer: The value of test statistic = -10.67
Step-by-step explanation:
Test statistic for proportion:

, where p= population proportion
n= sample size
= sample proportion
AS per given,
p=0.94, n= 1004, 

i.e. the value of test statistic = -10.67
T= Total cost
m= # of members
Total equals $60 fee plus ($15 times # of members) plus $95 fee plus ($12 times # of members)
T= $60 + $15m + $95 + $12m
combine like terms
EXPRESSION:
T= $27m + $155
Hope this helps! :)
Answer:
The probability of selecting two democrats is 1/380
Step-by-step explanation:
- Probability is the branch of mathematics that deals with numerical descriptions of how likely an event is to occur.
- Probability of an event = Number of favourable outcomes / Total number of outcomes.
Here we are given the people as,
8 democrats, 8 republicans and 6 independent.
So total number of people are: 8+6+6=20
Probability of choosing first democrat = 1/20
Probability of choosing first democrat = 1/19
Thus P( two democrats in succession ) = 1/20 ×1/19
= 1/380
