Answer:
He may be more worried about the flash than he is admitting.
Explanation:
Rod Sterling's play "The Monsters Are Due On Maple Street," tells an occurrence at a community in Maple Street where a sudden flash of light sent everything stuck. The appliances stopped working, cars stop running and it seems like every little thing was made to come at a standstill with that one flash of light in the sky.
The given conversation from Act I of the play shows the two men Steve and Charlie planning to got to town to inquire about the shortage. This was right after Tommy told them <em>"stories"</em> about an alien invasion and how <em>"they"</em> would want them to not go anywhere. The stage direction reveals Don Martin <em>"smil[ing] nervously"</em> which seems to suggest that <u>he is a bit scared and nervous about the flash than he dares to admit or show.</u>
Explanation:
We are given:
sample size= n = 45
sample mean = x = 61,300
sample standard deviation =18,246
Since the population standard deviation is not known we will use t distribution to find the confidence interval.
Confidence interval = 99%
Degrees of freedom= n - 1 = 45 – 1 = 44
Critical t value = 2.692
The 99% confidence interval will be:![(x-t_{critical}* \frac{s}{ \sqrt{n} }, x+t_{critical}* \frac{s}{ \sqrt{n} }) \\ \\ (61300-2.692* \frac{18246}{ \sqrt{45} }, 61300+2.692* \frac{18246}{ \sqrt{45} }) \\ \\ (53978,68622)](https://tex.z-dn.net/?f=%28x-t_%7Bcritical%7D%2A%20%5Cfrac%7Bs%7D%7B%20%5Csqrt%7Bn%7D%20%7D%2C%20x%2Bt_%7Bcritical%7D%2A%20%5Cfrac%7Bs%7D%7B%20%5Csqrt%7Bn%7D%20%7D%29%20%5C%5C%20%5C%5C%20%2861300-2.692%2A%20%5Cfrac%7B18246%7D%7B%20%5Csqrt%7B45%7D%20%7D%2C%2061300%2B2.692%2A%20%5Cfrac%7B18246%7D%7B%20%5Csqrt%7B45%7D%20%7D%29%20%5C%5C%20%5C%5C%20%2853978%2C68622%29)
Thus, the 99% confidence interval for the population mean is:
53978 to 68622
