The answer to your question is most likely A
This answer is B because it’s negative and less thsn
Answer:
Null hypothesis:
Alternative hypothesis:
Since the p value is very low compared to the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true percent of people with type A of blood is significantly different from 0.4 or 40%
Step-by-step explanation:
Information given
n=144 represent the random sample taken
X=81 represent the number of people with type A blood
estimated proportion of people with type A blood
is the value that we want to verify
represent the significance level
z would represent the statistic
Alternative hypothesis:
the statistic is given by:
(1)
Replacing the info given we got:
Now we can calculate the p value with this probability taking in count the alternative hypothesis:
Since the p value is very low compared to the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true percent of people with type A of blood is significantly different from 0.4 or 40%
Corresponding angles are angles that are equal in degrees and in this case it is <8 and <4 but there is also <5 and<7.
Answer:
16
Step-by-step explanation:
Let "a" represent the measure of the angle. Then ...
5a -30 = 2a +18
3a = 48 . . . . . . . add 30-2a
a = 16 . . . . . . . . . divide by 3
An angel is beyond measure, but this angle has measure 16.
