To find the perimeter of a square, just add up all the lengths of the sides: The area of a square: To find the area of a square, multiply the lengths of two sides together... Another way to say this is to say "square the length of a side!" and for the rectangle, The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.

Answer:

a)  t_{0.035},11=\pm2.201

b)  t=-2.963

c)  Reject\ H_0\ when\ \alpha=0.05

d)   t

   -2.963

Step-by-step explanation:

From the question we are told that:

Sample size n=12

Mean \=x=42.5

Standard deviation \sigma=3.8

Population mean \mu=45.75

Significance \alpha=0.05

 

Generally the hypothesis given by

H_0;\mu=45.75\\H_1:\neq =45.75

Generally the equation for test statistics is mathematically given by

t=\frac{\=x-\mu}{\sigma/\sqrt{n} }

t=\frac{42.5-45.75}{3.8/\sqrt{12} }

t=-2.963

Generally the Critical value is mathematically given by

t_{\alpha/2},d_t

\alpha=0.05 \\\alpha/2=0.025\\d_t=n-1=11

t_{0.035},11

From table

t_{0.035},11=\pm2.201

Therefore

t

-2.963

Reject\ H_0\ when\ \alpha=0.05
