A teacher surveyed her closs eher they had taken a vocabulary test. Elghteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The
test results (expressed as a percent) for the two groups are shown below.
Studied. 87, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 96, 100, 93, 96, 83
Did Not Study 82, 72, 45, 91,
58, 83, 65, 87, 90, 77, 73, 89
Part 1. Calculate the mean of the group that did not study, rounded to the nearest tenth.
Port 2: Calculate the mean absolute deviation of the group that did not study, rounded to the nearest tenth.
Part 3. How many of the scores from the group that did not study) are more than two mean absolute deviations from the
mean?

the forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.
