Answer:
Sierra's team has a greater percent of left-handed batters.
25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.
Step-by-step explanation:
Sierra: 7/28 = 1/4
1/4 written as a percentage is 25%
Aubrey: 5/25 = 1/5
1/5 written as a percentage is 20%
25% is greater than 20%, so Sierra's team has a greater percent of left-handed batters.
25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.
Hope this helps ;)
Answer:
1877 computer users
Step-by-step explanation:
We have that for 95% of confident, the value of z has a value of 1.96 (attached table about it), they also mention the margin of error (E) that is 10 and finally the standard deviation (sd) that has a value of 221.
We apply the following formula:
n = [z * sd / E] ^ 2
replacing:
n = [1.96 * 221/10] ^ 2
n = 1876.27
that is, the minimum sample size is 1877
