The hypothesis is given as

H0:  μd< 0

H1: μd > 0

<h3>How to solve for the hypothesis.</h3>

The null hypothesis is given as

H0:  μd< 0

<h3>The alternative hypothesis is given as </h3>

H1: μd > 0

SWe have to find the value of s

we would use this formula s = sqrt [ (Σ(di - d)^2 / (n - 1) ]

This gives us  3.454

Next we have to determine the standard error

s / √(n)

3.454/2.8284

= 1.22

Degree of freedom = 8 - 1

= 7

t = (x1 - x2) - D / S.E

=  1.025

Find t critical at 0.10

= 1.895

P-value = 0.1697

d. Given that p value is greater thatn 0.1 we fail to reject the null hypothesis.

The cross-sectional areas of a triangular prism and a right cylinder are congruent. The triangular prism has a height of 5 units
nydimaria [60]

Answer:

  The volume of the prism is equal to the volume of the cylinder

Step-by-step explanation:

For each solid figure, the volume formula is ...

  V = Bh

where B is the cross-sectional area and h is the height. The problem statement tells us B and h have the same values for both figures. Hence their volumes are the same.
