Answer:
Since the 5 in 357 is in the tens digit, it is 5*10=50, and the 5 in 465 is in the ones digit, so it is 5*1=5. 5≠50
Answer:
C) There is roughly a 95% chance that the resulting sample proportion will be within 0.04 of the true proportion.
Step-by-step explanation:
Given that 20% of the residents in a certain state support an increase in the property tax.
Sample size = 400
We want the sample proportion to be within 0.04 of the true proportion (i.e., between 0.16 and 0.24)
i.e. margin of error <0.04
Std error of sample = 
Critical value = margin of error/ std error = 
We know z value for 95% two tailed roughly equals 2.
Hence 95% confidence is right.
C) There is roughly a 95% chance that the resulting sample proportion will be within 0.04 of the true proportion.
70x + 490=1050
-490 -490\
70x= 560
divide both sides by 70
x = 8
