Claim: the standard deviation of pulse rates of adult males is more than 11 bpm. For a random sample of 171 adult males, the pulse rates have a standard deviation of 11.4 bpm find the value of the statistic

182.58842

Step-by-step explanation:

Given that:

Sample size (n) = 171

Population standard deviation σ = 11

Sample standard deviation s = 11.4

males is more than 11 bpm. For a random sample of 171 adult males, the pulse rates have a standard deviation of 11.4 bpm find the value of the statistic

The test statistic :

X² = ((n - 1) / σ²) * s²

X² = ((171 - 1) / 11²) * 11.4²

X² = ((170) / 121) * 129.96

X² = 1.4049586 * 129.96

X² = 182.58842

10 you would take 50/ .2

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
