Answer:

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
