Answer:
b. T.DIST
Step-by-step explanation:
Previous concepts
The t distribution (Student’s t-distribution) is a "probability distribution that is used to estimate population parameters when the sample size is small (n<30) or when the population variance is unknown".
The shape of the t distribution is determined by its degrees of freedom and when the degrees of freedom increase the t distirbution becomes a normal distribution approximately.
The degrees of freedom represent "the number of independent observations in a set of data. For example if we estimate a mean score from a single sample, the number of independent observations would be equal to the sample size minus one."
Solution to the problem
a. RAND
False, since this function is to generate a random number between 0 and 1. And is not used to calculate p values
b. T.DIST
Correct, since th population deviation is unknown and if we find the degrees of freedom we can calculate the p value with this function.
c. NORM.S.DIST
False, because this is in order to calculate the p value when the population deviation is given
d. Not enough information is given to answer this question.
False we have enough info to conclude this.
Answer:
6+ 2
Step-by-step explanation:
x= 6
y= 2
hope it helps !!
The use of mental method to add with decimals is similar to the mental method we used to add whole numbers because the decimals number can also change to whole numbers.
This is the reason the mental method for both are similar. we can also use the same process for decimal numbers and whole numbers.
I think the answer is they are similar by SSS, but they are definitely similar
