Answer with explanation:</h2>
As per given , we have
Since , alternative hypothesis is right tailed, so the test is a right tailed test.
n= 1987
Proportion of adults believe that rudeness is a worsening problem : 
Test statistic : 
(since , the normal curve takes values of z from -7 to 7, so we use critical value to draw conclusion.)
The critical value for a significance level of 0.005= 1.645
Since , absolute test statistic value (12.09) is greater than the critical value (1.645), it means there is statistical significance and so we reject the null hypothesis.
0.003 is 1/10 of 0.03.
Just multiply the 0.003 by 10 and you'll get the answer.
Answer:
The pressure at 50 feet is 2.51515 atm
Step-by-step explanation:
we are given equation as
where
p(d) gives the pressure, in atmospheres (atm)
a depth d in the sea (d is in feet)
We are given
d=50 feet
So, we can plug d=50 and find p
So,
The pressure at 50 feet is 2.51515 atm
