Answer:
=NORM.INV(0.17,98,15)
Step-by-step explanation:
Consider X represents the IQs of sample participants.
Then X follows the Normal Distribution with mean 98 and standard deviation 15.
That is,
The probability value is 17th percentile (that is 0.17)
To find the value of X using Excel, the<em> Inverse Normal Distribution </em>is used.
The Excel function =NORM.INV(0.22,105,17) is used to find the IQs of sample participants.
4(5x - 2) - 2(9 - 3x)
= 26x - 26
Answer:
The kind of error the researcher has done is a;
Type I error
Step-by-step explanation:
When carrying out hypothesis testing in statistical analysis, a type I error is the type of error said to have occurred when a null hypothesis that is true or correct is rejected which is a false positive conclusion
Given that that sugar box manufacturing company makes the boxes to be 100 g accurately, and that the researcher makes non-random or randomly selects packets which are not filled, the mean of the filled packets is expected to be 100 g making the conclusion for rejection of the null hypothesis a false positive rejection
I think it is A,C and E
Sorry if it’s wrong I havnt done these in a while. Hope this helps!
It is B y = 2x + b so that is the answer
