Not sure if I quite understand your question. But ill assume that you're asking if 1 times 7 is positive. Or if 1x7 is positive.
1 times 7 equals 7 so it is a positive integer.
1x7 can be positive or negative depending on what x equals. If x is a negative number then the whole expression is negative. If x is postive the expression is positive.
The 90% confidence interval for the true difference between the population proportions is [ - 0.0908, - 0.0092]
Given,
= 731
= 644
= 0.33
= 0.28
z score for 90% confidence interval = 1.645
Here, the confidence interval formula :
( 
) ± z 
Substituting the values, we get
(0.33 - 0.28) ± 1.645 
= 0.05 ± 1.645 
= 0.05 ± 1.645 
= 0.05 ± 1.645 × 0.0248093914
= 0. 05 ± 0.0408114489
Confidence interval:
- 0.05 - 0.0408114489 = - 0.0908114489 ≈ - 0.0908
- 0.05 + 0.0408114489 = - 0.0091885511 ≈ - 0.0092
The confidence interval for the true difference between the population proportions is [ - 0.0908, - 0.0092]

There are 3 tens in 230 and 23 tens in 230. They are both right
In number 230
2 is in hundreds place
3 is in tens place
and 0 is in ones place
so we can say 3 is in tens place
In number 230,
23 times 10 = 230
So we can says 23 tens is in 230
Hence 3 is in tens place in 230 and 23 tens in 230 are same
3 tens in 230 and 23 tens in 230 are not same .
