Answer:
discount amount=Rs. 130
selling price=Rs. 1170
Step-by-step explanation:
discount amount=10%of Rs.1300
=10/100*1300
=1300/10
=Rs. 130
selling price=MRP-discount amount
=1300-130
=Rs. 1170

Answer:
We conclude that population mean is equal to 100 at the α=0.01 level of significance.
Step-by-step explanation:
Given information:
Sample size, n=40
Sample mean=104.3
sample standard deviation, s=18.2
We need to check whether the population mean greater than 100 at the α=0.01 level of significance.
Null hypothesis:
Alternative hypothesis:
Let as assume that the data follow the normal distribution. It is a right tailed test.
The formula for z score is
Using the standard normal table the p-value at z=1.49 and 0.01 level of significance is 0.068112.
(0.068112 > 0.01) p-value is greater than α, so we accept the null hypothesis.
Therefore, we conclude that population mean is equal to 100 at the α=0.01 level of significance.
