Answer:

<em>The range of p-values </em>

<em>0.01 < p < 0.025 </em>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given random sample size 'n' = 7

Assume that the populations are normally distributed

Null Hypothesis :H₀:μd=0.

Alternative Hypothesis:H₁:μd<0.

Degrees of freedom

ν = n-1 =7-1 =6

given the test statistic  t = - 3.201

we will use single tailed test in t-distribution table

<em>The test statistic t= 3.201 is lies between the critical values is 0.01 and 0.025</em>

<em>The range of p-values </em>

<em>0.01 < p < 0.025  (check t- distribution table single tailed test) </em>

<u><em>Final answer:- </em></u>

<em>The range of p-values </em>

<em>0.01 < p < 0.025 </em>

How many triangles can be constructed with angles measuring 50,90,40
inn [45]
Only two triangles:
The 90* angle is stable, so you can change only the position of the 50* and 40* angles.
1 triangle: 40* is right to the 90*
2 triangle: 40* is left to the 90*

Hope this helped you!

1. A Square shaped wooden plate has a diagonal length of 30cm. Can you find the Perimeter of plate ?
DerKrebs [107]

Answer:

84.85cm

Step-by-step explanation:

Let the sides of the square be x

The perimeter of the square = 4x

Get x using the pythagoras theorem

x^2 + x^2 = 30^2

2x^2 = 900

x^2 = 450

x = 21.21cm

Perimeter of the plate = 4(21.21)

Perimeter of the plate = 84.85cm
