Step-by-step explanation:
It's clear that the ratio of the weight and cost is 1:2.
So when you increase the factor by 4 , the cost increases by 8.
That's all I can say, and I'm sure my answer is correct.
Answer:
Now we can calculate the p value with this probability:
If we use a significance level os 0.05 we see that the p value is lower than the significance level so then we can conclude that the true proportion of students with jobs is higher than 0.35 for this case. If we decrease the significance level to 1% the result changes otherwise not.
Step-by-step explanation:
Information given
n=78 represent the random sample taken
X=36 represent the students with jobs
estimated proportion of students with jobs
is the value that we want to test
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the proportion of students with jobs is higher than 0.35, the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info we got:
Now we can calculate the p value with this probability:
If we use a significance level os 0.05 we see that the p value is lower than the significance level so then we can conclude that the true proportion of students with jobs is higher than 0.35 for this case. If we decrease the significance level to 1% the result changes otherwise not.
Hello!
Convert 55% to a decimal by dividing it by 100.
55 ÷ 100 = 0.55
Next, multiply the total amount of ounces of water by this decimal.
32 × 0.55 = 17.6
Finally, subtract the amount of ounces that person drank from the total number of ounces before they drank.
32 - 17.6 = 14.4
ANSWER:
14.4 ounces of water are left in the glass.
