The length (in seconds) of cellular phone calls in an industrial zone has a normal distribution. Suppose that, from a random sample of lengths, the t based 90% confidence interval for the population mean length is (83.4, 109.7) seconds. On the basis of the same sample, would H₀: $\mu$ =83.8 be rejected in favor of H₁: $\mu$ $\neq$ 179.1 at $\alpha$ =0.01?
Answer the question "Yes", "No", or Cannot tell".

The Answer of The length (in seconds) of cellular phone calls in an industrial zone has a normal distribution. Suppose that, from a random sample of lengths, the t based 90% confidence interval for the population mean length is (83.4, 109.7) seconds. On the basis of the same sample, would H₀: $\mu$=83.8 be rejected in favor of H₁: $\mu$$\neq$179.1 at $\alpha$=0.01? Answer the question "Yes", "No", or Cannot tell".
