The department of public safety has an old memo stating that the number of accidents per week at a hazardous intersection varies

ELEN [110]

Answer:

P-value = 0.1515

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 2.2

Sample mean, $\bar{x}$ = 2

Sample size, n = 52

Alpha, α = 0.05

Population standard deviation, σ = 1.4

First, we design the null and the alternate hypothesis

$H_{0}: \mu =2.2\\H_A: \mu < 2.2$

We use one-tailed(left) z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{2 - 2.2}{\frac{1.4}{\sqrt{52}} } = -1.03$

Now, we calculate the p-value from the normal standard table.

P-value = 0.1515

Answer:

12 seconds

Step-by-step explanation:

Given

$y = -2.5x + 30$

Required

Determine the time taken to reach the ground

For the paper to reach the ground, y = 0

So, we have:

$y = -2.5x + 30$

$0 = -2.5x + 30$

Collect Like Terms

$2.5x +0 = 30$

$2.5x = 30$

Divide through by 2.5

$2.5x/2.5 = 30/2.5$

$x = 30/2.5$

$x = 12$

Hence:

Time taken is 12 seconds
