Downtown Store North Mall Store
Sample size n 25 20
Sample mean
$9 $8
Sample standard deviation s $2 $1




Standard error of difference of means = 
Standard error of difference of means = 
Standard error of difference of means = 
Degree of freedom = 
Degree of freedom = 
Degree of freedom =36
So, z value at 95% confidence interval and 36 degree of freedom = 2.0280
Confidence interval = 
Confidence interval = 
Confidence interval = 
Hence Option A is true
Confidence interval is 
Answer:
8820
Step-by-step explanation:
Prime factorization of 294,
→ 2 × 3 × 7 × 7
Prime factorization of 1260,
→ 2 × 2 × 3 × 3 × 5 × 7
LCM of 294 and 1260,
→ 2 × 2 × 3 × 3 × 5 × 7 × 7
→ 8820
Hence, the LCM is 8820.
