In an Asian country, the average height of females who were born between 1940 and 1960 was 159 cm, according to a survey conducted in 1980s. Researchers are wondering if later generations of females in that country are generally taller than older generations, so they collected height data from 100 females randomly drawn form the population born between 1980 and 2000 in that country.

The sample data represent the "later" generation while 159 is the average of the "older" generation.

Conduct a two-tailed one-samplettest to answer the research question, with = .05.

What is thetstatistic? What is the probability of the null hypothesis being true? What is the standardized effect size? What is the raw effect size?

What is the most appropriate answer to the research question?

a. The new generation of females are significantly shorter than the older generation of females in that country.

b. The new generation of females are not significantly taller than the older generation of females in that country.

c. The new generation of females are not significantly different from the older generation of females in height.

d. The new generation of females are significantly taller than the older generation of females in that country.
