Answer:
2 1/2
Step-by-step explanation:
2 1/2 = 5/2 = 2.5
now you can see that 2.5 > 2.3 so 2 1/2 is greater

Answer:
0.4
Step-by-step explanation:
n × 0.2=0.08
n = 0.08÷0.2
n = 0.4
Answer:
There is a significant difference between the means of the two population
Step-by-step explanation:
The mean number of catfish caught daily at Lake Martin is 85, with the number of catfish ranging from 75 to 140.
Range = 140 - 75 = 65
The mean number of catfish caught daily at Smith Lake is 104, with the number of catfish ranging from 96 to 183.
Range = 183 - 96 = 87
Difference in mean = 104 - 85 = 19
If the confidence interval includes 0 we can say that there is no significant difference between the means of the two populations, at a given level of confidence
But by considering the mean difference and the value of range, we can say that
There is significant difference between the means of the two population
