Answer:
Step-by-step explanation:
The p value (probability of obtaining results as extreme the z score if null is true) is usually the value derived to make a conclusion and in this case the p value is 0.03
The level of significance is the value usually compared with the p value which is 0.05
The sample promotion is 65 out of 100 = 65/100 = 0.65
The sample size is the total number of consumers which is 100
The null value is usually the default value. The null value would assume that there is no difference in the proportions who prefer each type in the population. There are two preferences: 100/2 = 50- 0.5 for each preference.
10-- 10,20,30,40,50,60,70,80,90
15-- 15,30,45,60,75,90,105
here are a few. The LCM would be 30.
I hope this helps!!
<span>x in (-oo:+oo)
(8/9)*x = (4/9)*x+8 // - (4/9)*x+8
(8/9)*x-((4/9)*x)-8 = 0
(8/9)*x+(-4/9)*x-8 = 0
4/9*x-8 = 0 // + 8
4/9*x = 8 // : 4/9
x = 8/4/9
x = 18
x = 18
