Question
A student was interested in the microscopic anatomy of organisms called water molds. These organisms produce large, spherical structures called oogonia that contain the large, sexual spores called oospores. She was curious if there was a relationship between oogonium diameter (size) and the number of oospores inside. She randomly sampled 30 oogonia from an individual strain of water mold, measured the diameter of the oogonium in m ,and counted the number of oospores inside.
Which represents the null hypothesis? Which best represents the alternative hypothesis?
A. µ1 = µ2,
B. µ1 µ2
C. µ1 > µ2
D. µ1 < µ2
E. µ1 µ2
F. µ1 µ2
G. 1 = 2
H. 1 2
I. 1 > 2
J. 1 < 2
K. 1 2
L. 1 2
M. = 0
N. 0
O. = 0
P. 0
Q. These data are consistent with a normal distribution.
R. These data are not consistent with a normal distribution.
S. The variances of the variables are approximately equal.
T. The variances of the variables are not equal.
Explanation / Answer
Null Hypothesis would be
M. = 0
Alternate Hypothesis would be
N. 0
Because we are interested in determine whether the relationship between the variable is occur or not
