Answer:
Type 2 error
Step-by-step explanation:
H0 : μ = 261
H0 : μ > 261
By failing to reject H0 ; when the it is false. This means accepting null hypothesis when it is actually FALSE. Then a type 2 error has been committed.
This is different from a type 1 error whereby the null hypothesis is rejected when it is actually TRUE.
Hence, by finding no evidence to reject the null hypothesis during statistical testing when the actual windspeed of an F5 tornado during statistical testing is actually greater than 261 mph.
Answer:
Step-by-step explanation:
Area of Alfred's land = (x²- 25)
Factors of given expression = (x - 5)(x + 5)
Therefore, Alfred's land will have the dimensions (x - 5) and (x + 5).
Area of his neighbor's land = x² + 3x + 2
Factors of the given expression = x² + 2x + x + 2
= x(x + 2) + 1(x + 2)
= (x + 1)(x + 2)
Therefore, dimensions of Grace land will be (x + 1) and (x + 2).
