Respuesta :

Answer:

A) There are no Counts

B) I'll count the number of each type of nut.

Step-by-step explanation:

A) Yes, the Chi-square is not an appropriate method because the question gave us the weight of the nuts in grams and these are not counts. Whereas, the chi-square goodness-of-fit test requires that the data values are counts.

B) What i will do instead is that i will count the number of each type of nut and assume that the given percentages are also relevant for each type of nut.
