Question

step 3 of 5: find the p-value associated with the test statistic. round your answer to four decimal places.

Answer 1

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.

What is known as a decimal mark?

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.
