The Z-statistic for this hypothesis test was z = -2.95. Based on this 2-statistic, what is the P-value and what is
the conclusion the researchers should reach for this
test?

A study was performed to investigate whether teens and
adults had different habits when it comes to consuming
meat-free meals. In particular, the researchers were
interested in the relationship between pa, the proportion
of teens who would report eating at least one meat-free
meal in the past week, and P2, the proportion of adults
who would report eating at least one meat-free meal in
the past week. A random sample of 875 teens and a
separate random sample of 2,323 adults found that 555
of the teens and 1,601 of the adults reported eating at
least one meat-free meal in the past week. The
conditions for inference were checked and verified.
The P-value = 0.0016 and, because this P-value is
very small, the conclusion should be that teens and
adults differ in the proportion of their meat-free meals.
O The P-value = 0.0031 an
very small, the conclusion should be that teens and
adults differ in the proportion of their meat-free meals.
O The P-value = 0.0016 and, because this P-value is
large, there is not enough evidence to conclude that
there is a significant difference in the proportions of
the meat-free meals that are ten by teens and
adults.

In a sample of 2023 u.s. adults, 373 said franklin roosevelt was the best president since world war ii. two u.s. adults are selected at random from the population of all u.s. adults without replacement. assuming the sample is representative of all u.s. adults, complete parts (a) through (d). (a) find the probability that both adults say franklin roosevelt was the best president since world war ii. the probability that both adults say franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (b) find the probability that neither adult says franklin roosevelt was the best president since world war ii. the probability that neither adult says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (c) find the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii. the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (d) which of the events can be considered unusual? explain. select all that apply. the event in part left parenthesis a right parenthesis is unusual because its probability is less than or equal to 0.05. the event in part (b) is unusual because its probability is less than or equal to 0.05. none of these events are unusual. the event in part (c) is unusual because its probability is less than or equal to 0.05.

Aadc is formed by reflecting aabc across line segment ac, as shown in the figure. if the length of ac is 4 units, the area of aadc is square units.
