Answer:
Yes
Step-by-step explanation:
Given that :
CHAIN A:
Sample size n1 = 30
Sample standard deviation of waiting time s1 = 21.2
CHAIN B:
Sample size, n2 = 28
Sample standard deviation of waiting time s2 = 31.4
Null hypothesis H0: s1 = s2
Alternative hypothesis H1: s1 < s2
Test statistic ; Ftest : s1² / s2²
Ftest = 21.2^2 / 31.4^2
= 0.4558399
P value from F statistic : = 0.02 (using p value calculator)
Since the pval < 0.05
Then we reject the Null ; Chain A waiting time is more consistent
Answer:
basically you have to calculate the perimeter-
Step-by-step explanation:
4+4+0.8+0.8=8+1.6=9.6
He has 10 pairs of shoes.
10 for 5 so to get 20 you multiply 10 by 2 so do the same to 5 and you’ll get 10
Answer:
a)8×83/100%
=8×83
=664
=664÷100%
=6.64%
b)2×83/100%
=2×83
=166
=166÷100%
=1.66%
c) a+b
=6.64%+1.66%
=8.3%
=8%
Step-by-step explanation:
a)8 debit card Customers × 83 cash ÷ 100%
=664÷100%
=6.64
b)2 credit card×83cash÷100%
=166÷100%
=1.66%
c) a+b
=6.64+1.66
=8.3%
=8%
