Answer:
The p value can be founded with the following probability:
Step-by-step explanation:
Information given
represent the sample mean
represent the population deviation
sample size
represent the value to verify
z would represent the statistic
represent the p value
System of hypothesis
We want to check if the true mean for this case is higher than 26, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info we got:
The p value can be founded with the following probability:
Z-score = (2.3 - 2.7)/(0.4/√15) = -0.4/0.1033 = -3.87
Answer:
y=22.6x+52.332020
Step-by-step explanation:
Answer: 9.4
Step-by-step explanation:
Here the x-coordinates and y-coordinates have the inverse relation.
⇒ 
⇒ 
Where k is variation constant.
Since, point (9.4, 11) is from the inverse variation,
Therefore, this point must be satisfy the above condition,
That is, 
Thus, the relation between the coordinates is,
Put x = 11, in the above function,
The y-intercept is (0,1)
⬇️
F(x)=(1/3)^x
f(0)=(1/3)^0
F(0)=1
