The alternative and null hypotheses is given below,

Null Hypothesis, H0: μ1 - μ2 = 0

Alternative Hypothesis, Ha: μ1 - μ2 < 0

Compound Variance is given as,

sp = sqrt( s12n1+s22n2)

sp = sqrt(16973 + 112.3673)

sp = 1.9632

Test statistic of z is,

z = (x1bar - x2bar)/sp

z = (69 - 71)/1.9632

z = -1.02

P-value Approach, P=0.1539 as long as P>= 0.

As P-value >= 0.01, failing to rule out the null hypothesis.

<h3>What is known as a decimal mark?</h3>

To differentiate between a whole number and its fractional component, a decimal point is used either as a point or a dot. It is also referred to as a decimal mark. The symbol for the decimal point is (.). In daily life, decimals are also frequently used. That whenever a shirt costs $10.50, for instance, the price can be written as 10.50.

Mrs.Smith has two similiar recycling bins in her office. The dimension of the smaller bin can be found by dilating the dimension
nikklg [1K]

Answer:

The dimension of the larger bin is x and the smaller bin is 0.75x.

Step-by-step explanation:

Let the dimension of the larger bin is x.

It is given that the dimension of the smaller bin can be found by dilating the dimension of the larger bin by a scale factor of 0.75

In order to find the dimension of the smaller bin multiply the dimension of the larger bin by 0.75

(x)(0.75)=0.75x

Hence, the dimension of the larger bin is x and the smaller bin is 0.75x.

3241004551 [841]
Answer:

first option: Harulo is correct because the angle is coterminal with 3π / 4 and the reference angle is π / 4.

Explanation:

1) 19 π/4 = 4π + 3 π/4, which is 4 complete turns and 3/4 of turn.

2) 3 π/4 is in the third quadrant, so the reference angle is π - 3 π/4 = π/4

3) sin (π/4) = sin (3π/4) = (√2) / 2

4) csc (π/4) =  1 / [ sin (3π/4) ] = 1 / [ (√2) / 2 ] = 2 / (√2) = √2, which shows the validity of the statement and csc(19π/4) = √2.
