Answer:
a) P=0.03
b) α=0.05
c) 0.72
d) 100
e) 0.72
Step-by-step explanation:
a) The P-value is the probability of the sample result. In this case the P-value is 0.03.
b) The level of significance is the threshold of probabilty for the null hypothesis to be reejcted or not. It is contrasted with the P-value to know if the effect is significant. In this case, the level of significance is 0.05.
NOTE: if it is a two-side test, the level of significance is 0.1 (two times 0.05).
c) The sample proportion is the one that results from the sample data. In this case, the sample proportion is 0.72.
d) The sample size is the amount of consumers reported. In this case is 100 customers.
e) The null value is 0.72 (equal to the sample proportion), because it is tested if there is no difference between the population proportion and the sample proportion.

Answer:
The line is
Step-by-step explanation:
From the question we are told that
The line is
The point is P(0,0 )
Generally the equation for a line is
Now comparing this with the given equation we see that
Generally the slope of the perpendicular to the given line is mathematically evaluated as
=>
=>
Generally from the univesal equation of a line and the given point we have that
y = mx + c at p(0,0) and is
0 = -4 (0 ) + c
=> c = 0
Hence the equation perpendicular to the line given at the point given is
