Answer:
Step-by-step explanation:
It can help to write more digits. If we write the numbers in the order they are in choice B, we have ...
- 7.1530
- 7.153153153...
- 7.15333333...
- 7.15353535...
- 7.15555555...
Looking down the list, you can compare digits left to right and tell that these are in smallest-to-largest order. The highlighted digits are the ones that place the number in its appropriate order

Answer:
95% two-sided confidence interval on the true mean breaking strength is (94.8cm, 99.2cm)
Step-by-step explanation:
Our sample size is 11.
The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So
.
Then, we need to subtract one by the confidence level and divide by 2. So:
Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 10 and 0.025 in the two-sided t-distribution table, we have
Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So
Now, we multiply T and s
cm
For the upper end of the interval, we add the sample mean and M. So the upper end of the interval here is
cm
So
95% two-sided confidence interval on the true mean breaking strength is (94.8cm, 99.2cm).
Answer:
$9.00
Step-by-step explanation:
If the price is at 30% discount, this means it is 100-30 = 70% of the original price.
Hence, original price is $9.00.
