Answer:

Step-by-step explanation:

From the information given:

For Adult Men

Mean \mu = 69.5

Standard deviation \sigma = 2.4

observed value X = 74

For Adult Women

Mean \mu = 63.8

Standard deviation \sigma = 2.6

observed value X = 70

Therefore ; the values for their z  scores can be obtained in order to determine who is more unusually tall within his or her respective sex

For Adult Men :

z = \dfrac{X- \mu}{\sigma}

z = \dfrac{74- 69.5}{2.4}

z = \dfrac{4.5}{2.4}

z = 1.875

For Adult Women :

z = \dfrac{X- \mu}{\sigma}

z = \dfrac{70- 63.8}{2.6}

z = \dfrac{6.2}{2.6}

z = 2.3846

Thus; we can conclude that , the women is more unusually tall within his or her respective sex
