Answer:
μ < 550
Step-by-step explanation:
Let us take,
Null Hypothesis(H₀) : μ = 550
Alternative Hypothesis(H₁) : μ < 550
Now, The Z-statistic for mean is given by,
Here, n = 36, μ = 550, = 530, s = 78
Z = (530 - 550) ÷ √(78 / 36)
Z = -20 ÷ 1.47196
Z = -13.58732
Thus, Z-value = -13.587 with 35 degree of freedom.
and α = 0.01
The value of p is < .00001.
Since, the value of p is less than α.
The result is significant at p < .01.
Thus, we reject the null-hypothesis.
Hence, μ < 550
