Answer:
The p value would be given by:
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true proportion is significantly less than 0.64 at 5% of significance
Step-by-step explanation:
Information given
n=145 represent the random sample taken
X=89 represent the number of people who believed the supermarket brand was as good as the national brand
estimated proportion of people who believed the supermarket brand was as good as the national brand
is the value to test
represent the significance level
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true proportion is less than 0.64, the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info we got:
The p value would be given by:
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true proportion is significantly less than 0.64 at 5% of significance
Steve's original temperature - 102
2 hours later it dropped 3 degrees
102 - 3 = 99
Steve's current temperature is 99.
Answer: x = 2/13
Step-by-step explanation:
9x-8=34x-12
Add 12 on both sides and you get
9x+4=34x
Subtract 9x from both sides and you get
4=26x
Divide 26 from both sides to get
X= 4/26
Simlify
x = 2/13
