Answer:
With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months
Step-by-step explanation:
The lower bound of the confidence interval is 29.9%.
So, with 95% confidence, we know that at least 29.9% of the New York population tested for HIV.
Out of 6 million, that is:
0.299*6000000 = 1,794,000
With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months
Answer:
Gail will need 12 yards of white fur, 8 yards of blue striped and 2 yards of the pink felt.
Step-by-step explanation:
We are given that,
The amount of yards for making one costume of different fabrics are,
White fur fabric = 
= 
yards
Blue striped fabric = 1 yard
Pink felt for ears = 
yards.
So, we have,
The amount required to make 8 costumes are,
White fur fabric = 
= 3×4 = 12 yards
Blue striped fabric = 1×8 = 8 yards
Pink felt for ears = 
= 2 yards.
Thus, Gail will need 12 yards of white fur, 8 yards of blue striped and 2 yards of the pink felt.
