Answer: The sample should include 542 men and 542 women.
Step-by-step explanation:
When the <em>prior estimate of the population proportion for both population 1 and population 2 are not available</em> , then we assume that it 0.5 i.e. both have equal chances.
Formula to find the equal sample sizes : , where z* = critical z-values associated with the given confidence level and E = Margin of error.
By considering the given information , we have
E= 0.05
Confidence level = 90% =0.90
Critical z-value for 90% confidence level : z*=1.645 (By z-table)
Now, the required sample sizes would be :
Hence, the sample should include 542 men and 542 women.
The probability of of the dial stopping on red slice is zero (0) because there was no red slice
Answer: $153.17
Step-by-step explanation:
85+85=$170
15% of $170 is $25.50.
170-25.50= $144.50
6% of 144.50=$8.67
144.50+8.67= $153.17
So, the answer is (B)-$153.17
The total price is $12.38. First you multiply $14.00 x .15 which equals $2.10. Then you subtract $2.10 from $14.00 which equals $11.90. The next step is to multiple $11.90 x . 04 which equals $0.48. Then you add $11.90 + $0.48 which equals $12.38.
5.35 i’m not sure but hope this helps
