Answer:
First Blank: 20 photos
Second Blank: 6 minutes
Third Blank: 45 Photos
Fourth Blank: 10 minutes.
Step-by-step explanation:
4*5=20 Photos
30/5=6 Minutes
9*5=45 Photos
50/5=10 Minutes
Answer:
the probability of the dice is 1/6 and the probability of the spinner is 1/4.
Step-by-step explanation:
the probability of the dice=E/S=E=1 and S=6 because it is one dice. so P=1/6.
the probability of the spinner=E/S=E=1 and S=4 because the spinner is divided into 4. so P=1/4

Answer:
1) p1=0.83
2) p2=0.81
3) Option B
4) p=0.82
5) s=0.03
6) z=0.67
7) P=0.50
8) Do not reject H0
Step-by-step explanation:
1) The proportion of Republicans who think the full-body scans should be applied in airports is equal to the ratio between the republicans that think it should over the total Republicans in the poll:

2) The proportion of Democrats who think the full-body scans should be applied in airports is equal to:

3) As we want to know if there is a difference in the proportions calculated, not if one is higher or lower than the other, the correct option is B:

4) The pooled estimate of a proportion is the average of both proportions:

5) The standard error can be calculated as:

6) The z-statistic can be calculated as:

7) The P-value for z=0.67 is P=0.50 (from the standard normal distribution table).

8) If the significance level is 0.01, the P-value is bigger than the significance level. The effect is not significanct. The null hypothesis is not rejected.
There is not enough evidence to say that both proportions are different.
A. Do not reject H0
