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

Which sentence does not contain any errors in the use of italics or quotation marks?

Having in mind that the italics are popularly used to call attention to certain words in a block of text and that some of the rules for quotation are: Use double quotation marks to set off a direct (word-for-word) quotation and Always capitalize the first word in a complete quotation, even midsentence. then the correct one here is the B option. Hope this can help
