A manufacturer claims that the mass of the widgets they produce is intended to be 9.2 grams. You, a quality control specialist, are hired to verify their claim. You take a random sample of 36 widgets and computed the sample mean and standard deviation which were 9.4 and 0.7 grams respectively.
1. Select the appropriate null and alternative hypothesis.
Select one:
a. H0: x = 9.2 vs. HA : x /= 9.2
b. H0: μ = 9.2 vs. HA: μ /= 9.2
c. H0 : p^ = 9.2 vs . HA : p^ /= 9.2
d. H0 : p = 9.2 vs. HA : p /= 9.2
e. H0: x = 9.4 vs. HA : x /= 9.4
f. H0: μ = 9.4 vs. HA: μ /= 9.4
g. H0 : p = 9.4 vs . HA : p /= 9.4
