0.029 grams is the average mass
Answer: 3/8 of the class went to the evening session.
Explanation:
So it says on Sunday 3/4 of an 8th grade class went to see the movie.But we do not know the real population of the 8th grade class. But is says that out of the 3/4 of the students that went to the movie have of them went in the afternoon so we will multiply 1/2 by 3/4 to find out how many people went to the afternoon session.
3/4 * 1/2 = 3/8 So we know that 3/8 of the 3/4 of the class went in the afternoon so we will now subtract 3/8 from 3/4 to find out what fraction went in the evening.
=
To think about it if half of the 3/4 of the class went in the afternoon then another have will go in the evening.
The software output implies that the researcher is 95 percent confident that the interval given regarding the beats per minute contains the true mean heart of the adults.
From the complete information, the margin of error will be calculated as:
= (Upper limit - Lower limit) / 2
where,
Upper limit = 73.325706
Lower limit = 68.509306
= (73.325706 - 68.509306) / 2
= 4.8164 / 2
= 2.4082
Also, it should be noted that in a situation where there is an increase in the confidence interval, this will lead to an increase in the margin of error.
