Zero is greater than 2, so second one from the left.
Answer: Rejecting the mean weight of each cake as 500 gram when H subscript 0 equals 500
Step-by-step explanation:
Given that :
Null hypothesis : H0 =500
Alternative hypothesis : Ha < 500
Type 1 Error: Type 1 error simply occurs when we reject the Null hypothesis when the Null is true. Alternatively, type 11 error occurs when we fail to reject a false null hypothesis.
Hence, in the scenario above, a type 1 error will occur when we reject the mean weight as 500 even though the Null hypothesis is True.
Answer:
Step-by-step explanation:
The formula for simple interest I is
I = Prt, where
P = the principal (amount invested)
r = the interest rate per period and
n = the number of periods
In this problem, the interest rate is annual, so n = 1.
We must write the interest rate as a decimal fraction.
Let x = amount of each investment. Then
0.02x = interest at 2 %
0.07x = interest at 7 %
0.09x = interest at 9 %
0.18x = total interest
Answer:
20 units
Step-by-step explanation:
Distance formula uses the Pythagorean Theorem
Distance D = root ( (9 - (-3))^2 + (10 - (-6) )^2 )
D = root ( 12^2 + 16^2 )
D = root ( 144 + 256) = root (400) = 20
