Answer: The answer is d. 16.530 m with 4 significant figures
Step-by-step explanation:
Significant figures are the digits that contribute meaning in the expression
In the given options
a.
Here only 2 and 6 are counted as significant digits
b.
Here Since the zeros are after decimal So they will not be counted in significant figure i.e. S fig =2
c. 0.108
Here No of significant figures will be 3
d. 16.530
Here the no of significant figures are 4 i.e 1 6 5 3
So the answer is d.16.530
Answer:
0.9256
Step-by-step explanation:
Given that a convenience store owner claims that 55% of the people buying from her store, on a certain day of the week, buy coffee during their visit
Let X be the number of customers who buy from her store, on a certain day of the week, buy coffee during their visit
X is Binomial (35, 0.55)
since each customer is independent of the other and there are two outcomes.
By approximation to normal we find that both np and nq are >5.
So X can be approximated to normal with mean = np = 19.25
and std dev =
Required probability = prob that fewer than 24 customers in the sample buy coffee during their visit on that certain day of the week
= (after effecting continuity correction)
= 0.9256
