Answer:
[ 502.5, 517.5]
Step-by-step explanation:
Given:
Mean of the sample, µ = 510
Total sample size, n = 100
Standard deviation = 75
Confidence level = 95%
Now,
The interval for µ is given as:
⇒ µ ± 
for 95% confidence level z value = 1.96
Thus,
The interval for µ
⇒ 510 ± 
or
⇒ 510 ± 7.5
or
⇒ [ 510 - 7.5, 510 + 7.5 ]
or
⇒ [ 502.5, 517.5]
Answer:
The distribution is Poisson distribution
Step-by-step explanation:
From the question we are told that
An expected number of fish was caught per hour is 1.5
The distribution that best characterize the number of fish you catch in one hour of fishing is the Poisson distribution
This because generally the Poisson distribution is a distribution that shows the number of times a given event will occur within a defined period of time
