The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (2, 5) and (4, 10). Substitute:

m=\dfrac{10-5}{4-2}=\dfrac{5}{2}=2.5

This means that 2.5mm of rain falls every hour

A study of 35 golfers showed that their average score on a particular course was 92. The sample standard deviation was 5. We wan
svlad2 [7]

Answer:

t_{\alpha/2} = t_{0.05/2} = t_{0.025} = 2.0322

Step-by-step explanation:

We have a sample of size n = 35, \bar{x} = 92 and s = 5. As we want to construct a 95% confidence interval to estimate the value of the true population mean \mu, we should use the pivotal quantity given by T = \frac{\bar{X}-\mu}{S/\sqrt{n}} which comes from the t distribution with n - 1 = 35 - 1 = 34 degrees of freedom. Besides we should use the t-value t_{\alpha/2} = t_{0.05/2} = t_{0.025} = 2.0322, i.e., regarding the t-distribution with 34 degrees of freedom, we have an area of 0.025 above 2.0322 and below the probability density function. The rationale behind this is that P(-2.0322\leq T\leq 2.0322) = 0.95 because of the simmetry of the t distribution.
