Answer:
z=14.73
p=0.000
for 99% confidence level the null hypothesis is rejected, thus majority of us adults would not bothered if the NSA collected personal records.
Step-by-step explanation:
: Half of US adults would not bothered if the NSA collect records of personal telephone calls
: Majority of the adults would not bothered if the NSA collect records of personal telephone calls
According to the sample, z-value can be found using the formula:
z= where
- X is the adults, who would not be bothered in the survey (397)
- M is the mean of the distribution of null hypothesis (257)
- n is the sample size (514)
- p is the proportion of the sample, who said they would not bothered (
≈ 0.77)
Putting these numbers in the formula,
z=14.73 and corresponding p value is p≈0.000
Since p<0.01, for 99% confidence level we reject the null hypothesis, thus majority of us adults would not bothered if the NSA collected personal records.
Answer: 1.44 centimeters cubed.
Step-by-step explanation:
To find the volume of a rectangular prism, use the following formula:
, where w equals the width, h equals the height, and l equals the length.
Substituting 0.6, 1, and 2.4 for the variables:
V = 0.6 * 1 * 2.4
V = 1.44 cm^3
The volume of the prism is 1.44 centimeters cubed.
