Answer:
Since is a bilateral test the p value would be:
Step-by-step explanation:
Information given
n=100 represent the random sample taken
estimated proportion of the readers owned a particular make of car
is the value that we want to test
z would represent the statistic
represent the p value
Hypothesis to test
We need to conduct a hypothesis in order to test if the true proportion is 0.31 or no.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
And replacing we got:
Since is a bilateral test the p value would be:
Compose the result function for y=2x - 7 by replacing function designators with the actual function y= 2x - 7
Answer:
<u>64 ivy stems</u>
Step-by-step explanation:
A wedding planner uses 72 ivy stems for 18 centerpieces.
for only need 16 centerpieces ⇒ she will use x ivy stems
