You are correct in saying that it is false to say that all isosceles triangles are congruent. They are indeed similar because the two remaining angles measure 45 degrees making all the isosceles right triangles equiangular. The sides should have the same ratio of the corresponding for them to be considered similar.
Answer: 56
Step-by-step explanation: because 8x7=56
Answer:
Decision rule: Do not reject ; we cannot conclude that the mean differs from zero
Step-by-step explanation:
From the given information:
The null hypothesis and alternative hypothesis is given as:
And the 99% confidence interval for the population mean is: [−3.79, 5.86]
The significance level ∝ = 1 - 0.99 = 0.01
We will notice that the 99% confidence interval for the population mean contains the null hypothesis mean value which is equal to zero.
Thus, we do not reject the null hypothesis at the significance level ∝ = 0.01
∴
Decision rule: Do not reject ; we cannot conclude that the mean differs from zero
