Answer:
false
Step-by-step explanation:
SA = 6 (edge X edge)
Volume of a cube = edgae x edge x edge
We have constructed the frequency distribution.
What is a frequency distribution?
In statistics, a frequency distribution is a graph or data set that shows the frequency of occurrence of each possible outcome of a repeatable event observed many times. Simple examples are election returns and test scores listed by percentile. A frequency distribution can be represented graphically as a histogram or a pie chart.
The frequency distribution table is shown below
Dormancy Period Frequency
55-59 1
60-64 0
65-69 1
70-74 4
75-79 0
80-84 7
85-89 3
90-94 5
95-99 4
100-104 3
105-109 1
110-114 0
115-119 1
N=30
Hence, we have constructed the frequency distribution.

Answer:
A. T > 2.539
Step-by-step explanation:
We have a hypothesis test of the mean, with unknown population standard deviation.
The hypothesis are:
From the hypothesis we can see that the test is right-tailed, so the critical value of t should be a positive value.
The degrees of freedom can be calculated as:
The significance level is 0.01, so the critical value tc should be the one that satisfies:
Looking up in a t-table, for 19 degrees of freedom, this critical value is tc=2.539.
