A study of traffic patterns in a large city shows that if the weather is rainy, there is a 50% probability of an automobile acci

dent occurring during the morning commute. If the weather is clear, the probability of an accident is reduced to 25%. Suppose the weather forecast for tomorrow predicts a 75% chance of rain.

Based on the data given, I would presume that the data will be 75 percent in the chance of also having an accident.
However, data is still insufficient. Thank you for your question. Please don't hesitate to ask in Brainly your queries.

In a certain city of several million people, 7.7% of the adults are unemployed. If a random sample of 300 adults in this city is
Lilit [14]

Answer: 0.2643

Step-by-step explanation:

Given : The proportion of  adults are unemployed : p=0.077

The sample size = 300

By suing normal approximation to the binomial , we have

\mu=np=300\times0.077=23.1

\sigma=\sqrt{np(1-p)}=\sqrt{300\times0.077(1-0.077)}\\\\=4.61749932323\approx4.62

Now, using formula z=\dfrac{x-\mu}{\sigma}, the z-value corresponding to 26 will be :-

z=\dfrac{26-23.1}{4.62}\approx0.63

Using standard distribution table for z , we have

P-value=P(z\geq0.63)=1-P(z

=1-0.7356527=0.2643473\approx0.2643

Hence, the probability that at least 26 in the sample are unemployed  =0.2643

Which of the following is a reasonable estimated answer to the following problem?
bulgar [2K]
989,867 \approx 1,000,000
999 \approx 1000

\implies  \frac{989,867}{999} \approx  \frac{1,000,000}{1000}
\frac{1,000,000}{1000} = 1000

So the answer is approximately 1000.
