Consider a t distribution with 7 degrees of freedom. compute p(-1.29 < t < 1.29). round your answer to at least three decimal places.
consider a t distribution with 18 degrees of freedom. find the value of c such that p(t< = c) = 0.05. round your answer to at least three decimal places.
p(-1.29 < t < 1.29) =
c =

Step-by-step explanation:

Given that there is a t distribution with 7 degrees of freedom.

P(-1.29 < t < 1.29)=1-0.2380

=0.7620

b) Now there is a different t distribution with 18 df.

When

c=-1.733

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
