ANSWER ASAP HUHUHU

A study is made to determine the force required to pull apart pieces of glued plastic. Three types of plastic were tested using 4
different levels of humidity. The results, in kilograms, are given as follows:
Plastic Type
Humidity
90%
33.0
30%
50%
70%
39.0
33.1
33.8
36.9
27.2
29.7
28.5
27.4
29.2
26.7
30.9
Use a 0.05 level of significance to test the hypothesis that there is no difference in the mean force required to pull the glued
plastic apart
(a) When the different types of plastic are used
(b) For different humidity conditions
