Answer:
The correct option is;
Yes because the computed t lies in the rejection region
Step-by-step explanation:
Here we have
The calculated mean of the values given as
= Sample mean = 41.5
μ = Population mean = 43
σ = Standard deviation 1.784
The confidence interval is
At 0.02 the critical t is 
2.718 with a p value of 0.014 which is less than the confidence level at 0.02. We therefore reject the null hypothesis and we fail to reject the alternate hypothesis which states that there has been a change in the mean length
Therefore the answer is Yes because the computed t lies in the rejection region.
Answer:
The number is: 775
Step-by-step explanation:
The prime numbers from 1-9 are: 2,3,5,7
To form the greatest three digit prime number where each of the digits is prime and the sum of all three digits is also prime:
- we have to start the number from 7 as the greatest prime number is 7.
- the next digit has to be also 7 so that the number remains bigger.
- if for the ones digit we take prime number seven than the sum of all the three digits will not be prime ( as 7+7+&=21 which is not a prime number).
so we take the digit 5 and the sum will be 19(7+7+5) which is a prime
number.
Hence the number is 775.
