Answer:
the probability that a sample of 4 bags will have a mean weight less than 9.8 pounds is 0.05
Step-by-step explanation:
Given the data in the question;
μ_x = 10 pound bags
standard deviation s_x = 0.24 pounds
sample size n = 4
The bag weights are normally distributed so;
p( x' less than 9.8 ) will be;
p( (x'-μ_x' / s_x') < (9.8-μ_x' / s_x') )
we know that;
μ_x' = μ_x = 10
and s_x' = s_x/√n = 0.24/√4
so; we substitute
p( z < ( (9.8 - 10) / (0.24/√4) )
p( z < -0.2 / 0.12 )
p( z < -1.67 )
{ From z-table }
⇒ p( z < -1.67 ) = 0.0475 ≈ 0.05
Therefore, the probability that a sample of 4 bags will have a mean weight less than 9.8 pounds is 0.05
"help..." said the high schooler.
"No," said Life, "figure it out yourself."
Then the rejected high schooler went to watch YouTube to relieve stress, hour and hours passed by until the high schooler realized he was wasting time.
"Oh no!" He said, "I have wasted time again! How will I ever get pass high school?"
"We will help you," said the flash cards, colored pens, and highlighters "we will be your best friend."
After that day, the high schooler never had an all nighter for the rest of high school. (College is a different story)
Moral of the story: Life and cute cat videos will not help you and your homework. Paying attention in class, making flash cards, making your notes colorful with pens and highlighter are what really helps :)
Oh and asking your teacher for help is great too.

Answer:
-1/5>-10/4
Step-by-step explanation:
In the negatives, If you take away the negative the lower number is more.
Think about a number line, if you are at -1/5, it means that you are 1/5 away from 0. If you are at -10/4, It means that you are 10,4 away from 0.
In conclusion, -1/5>-10/4
