6 the standard deviation of human body temperatures is equal to 0.62 F. identify the null hypothesis and alternative hypothesis in symbolic form

H₀: σ = 0.62

H₁: σ ≠ 0.62

Step-by-step explanation:

The null hypothesis is that the standard deviation σ is equal to 0.62.

The alternative hypothesis is that it does not equal 0.62.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
