Fifty-two billion, six hundred and thirty-four million, two hundred and seventy-five thousand, three hundred and nine.

**Answer:**

(a) The z-critical value for a left-tailed test, for a significance level of α=0.05 is -1.64.

(b) Since -1.54 > -1.64, therefore we accept H₀.

**Step-by-step explanation:**

(a)

It is given that the value of test statistic is

We need to test the claim that p<0.18.

Null hypothesis:

Alternative hypothesis:

It is a left tailed test.

Significance level:

**The z-critical value for a left-tailed test, for a significance level of α=0.05 is -1.64.**

(b)

It is a left tailed test and critical value is -1.64 it means the region on left of -1.64 is rejection region.

The value of z is -1.54 and the critical value is -1.64.

We know that -1.54 > -1.64.

**Therefore we accept H₀.**

0.43 is the answer, because 5 rounds up.

**Answer:**

**Step-by-step explanation:**

Let's find a solution by understanding the following:

The acceleration rate is defined as the change of velocity within a time interval, which can be written as:

where:

A=acceleration rate

Vf=final velocity

Vi=initial velocity

T=time required for passing from Vi to Vf.

Using the problem's data we have:

Vf=65miles/hour

Vi=6miles/hour

T=14.8seconds

Using the acceleration rate equation we have:

, but look that velocities use 'hours' unit while 'T' uses 'seconds'.

So we need to transform 14.8seconds into Xhours, as follows:

Using X=0.0041hours in the previous equation instead of 14.8seconds we have:

In conclusion, the acceleration rate is
