Answer:
I believe it takes 4 hours
Step-by-step explanation:
8400m ÷ 35m = 240 mins
240 mins = 4 hours
Response with clarification:
Let p denote the proportion of adults in the town who have encountered this flu strain.
According to the provided information

∵
this is a two-tailed test.
Test statistic:

, where p= denotes the population proportion
= signifies the sample proportion
n= represents the sample size
Setting n= 6 and
and p=0.08


P-value for the two-tailed test:[2P(Z>|z|)
=2P(Z>|-0.415|)
=2P(Z>0.415) = 2[1-P(Z≤0.415)] [∵ P(Z>z)=1-P(Z≤z)]
=2(1-0.6609) [from the z-table]
=0.6782
Decision: Because the p-value(0.6782) exceeds the significance level of 0.01, we do not reject the null hypothesis.
This leads us to conclude that there is insufficient evidence to back the assertion that the percentage of all adults in this town exposed to this flu strain deviates from the national average of 8%.
The temperature increased by 29°C, which indicates a positive change of 29. Then, it decreased by 29°C, reflecting a negative change. The average temperature experienced equal increases and decreases, leading to identical absolute values and resulting in a difference of 0.
Response:
B: 32 cm
To clarify, one should only sum the external measurements
6+6+4+4+3+3+3+3=32 cm
