Question

5. Food Preference:

A student conducted a study on food preference in 100 adult females. The study asked each adult if they preferred food that is salty or sweet. 65 answered salty and 35 answered sweet. Is there a difference in the observed vs. expected counts of salty vs sweet? (assume that the null hypothesis is no difference). (8)

Now the same student wanted to know if there a difference between the sexes in basic food preference. The student sampled an additional 100 males and the final results were: 65 females preferred salty and 35 preferred sweet. 46 males preferred salty and 54 preferred sweet. (8)
