Answer:  46

Step-by-step explanation:

Given : Margin of error : E= 17

Standard deviation : \sigma=70

Critical value for 90% confidence level :z_{\alpha/2}=1.645

Formula to find sample size is given by :-

n=(\dfrac{z_{\alpha/2}\times \sigma}{E})^2

i.e. n=(\dfrac{(1.645)\times 70}{17})^2

\Rightarrow\ n=45.880700692\approx46

Hence, the required minimum sample size = 46.

Ester sarai and kurry chose a number esters number is 1/10 of saris kurrys number is 10 times as much as sarais sarais number is
Tom [10]

Ester, Sarai, and Kurry each selected a number: 0.009, 0.09, and 0.9, respectively.

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes. For instance, 3+3+3+3+3 can be expressed as 3 5.

the ester's number is equal to one-tenth of the Sarai number.

= 1 / 10 × 0.09 = 0.009

to determine Kurry's number, multiply Sarai's number by 10

= 10 × 0.09 = 0.9

Therefore, it can be inferred that Kurry chose 0.9, Ester chose 0.009, and Sarai chose 0.09.
