The value of 27 is within 95% confidence interval because it is greater than 26.7 and less than 29.3.
<h3>What is a confidence interval?</h3>
In statistics, a confidence interval is a range to estimate for unknown terms.
The most common level is the 95% confidence interval.
It can be calculated by
CI = Mean ± margin of error.
α = 1 - 0.95 = 0.05
α/2 = 0.025
z(0.025) = 1.96
We need to find the 
= 0.645
So,
= 1.96 × 0.645
CI =1.26
C.I= 28±1.2652
Upper limit = 28+1.2652
=29.2625
Lower limit =28-1.2652
=26.7348
Hence, The value of 27 is within 95% confidence interval because it is greater than 26.7 and less than 29.3.

5 animals are going towards the river .
<u>Step-by-step explanation:</u>
Here we have , One rabbit saw six elephants while going to the river. Every elephant saw 2 monkeys going towards the river. Every monkey holds one parrot in their hand.We need to find How many animals are going towards the river . Let's find out:
- 1 rabbit saw 6 elephants while going to the river. i.e. rabbit is only going towards river !
- Every elephant saw 2 monkeys going towards the river. From the sentence , each of the 6 elephants saw 2 monkeys going towards the river, hence will be 6 x 2 = 12 monkeys going towards the river.
But, the statement does not explicitly say that “Every elephant saw 2 DIFFERENT monkeys…”, therefore implicit rules apply and infer that the 2 monkeys are the same. So , every elephant saw 2 monkeys!
- Now , every monkey holds 1 parrot in their hands. 2 parrots are going towards the river.
So , total number of animals is :
⇒ 
⇒ 
Therefore , 5 animals are going towards the river .
