Answer:
1.2
Step-by-step explanation:
Since we are rounding it by the tenth, it means we are rounding to the 1st digit to the right of the decimal.
We know 7 is greater then 5 meaning we round up
.1 + .1 is equal to .2 meaning its 1.2

Answer:
(0.0706, 0.1294)
Step-by-step explanation:
Confidence interval of a proportion is:
CI = p ± CV × SE
where p is the proportion,
CV is the critical value (z score or t score),
and SE is the standard error.
The sample is large enough to estimate as normal. For 95% confidence level, CV = z = 1.96.
Standard error for a proportion is:
SE = √(pq/n)
SE = √(0.1 × 0.9 / 400)
SE = 0.015
The confidence interval is:
CI = 0.1 ± (1.96)(0.015)
CI = (0.0706, 0.1294)
Round as needed.
5m : 100cm
= 5m : 1m
Therefore, the ratio is 5:1 which is answer c.
