The z-statistic for Brett's data is found to be as given by: Option A: -5.30 (approx).
<h3>How to find the value of z-statistic for population mean?</h3>
Suppose we're specified that:
- The sample mean =
- The population mean =
- The population standard deviation =
- The sample size = n
Then the z-statistic for this data is found as:
For this case, we've got:
- The sample mean = = 295
- The population mean = = 310
- The population standard deviation = = 20
- The sample size = n = 50
Thus, we get:
Thus, the z-statistic for Brett's data is found to be as given by: Option A: -5.30 (approx).

Answer:
Step-by-step explanation:
<u>Given Data:</u>
Speed = v = 36 km/h
Time = t = 35 mins = 35 / 60 = 0.58 hr
<u>Required:</u>
Distance = S = ?
<u>Formula:</u>
S = v × t
<u>Solution:</u>
S = 36 × 0.58
S = 21 km
