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:
x = -3
y = 1
Step-by-step explanation:
3x + 5y = -4
x + 5y = 2 (Solve for x) ------ New Equation: x = 2 - 5y
Solve for the first equation by plugging in the value of x, which is 2 - 5y.
3(2 - 5y) + 5y = -4
6 - 15y + 5y = -4
-10y = -10
y = 1
Use the value of y to solve for x
x + 5(1) = 2
x = 2-5
x = -3
