Answer:
A.)
H0: μ ≤ 31
H1: μ > 31
B.)
H0: μ ≥ 16
H1: μ < 16
C.)
Right tailed test
D.)
If Pvalue is less than or equal to α ; we reject the Null
Step-by-step explanation:
The significance level , α = 0.01
The Pvalue = 0.0264
The decision region :
Reject the null if :
Pvalue < α
0.0264 > 0.01
Since Pvalue is greater than α ; then, we fail to reject the Null ;
Then there is no significant evidence that the mean graduate age is more Than 31.
B.)
H0: μ ≥ 16
H1: μ < 16
Null Fluid contains 16
Alternative hypothesis, fluid contains less than 16
One sample t - test
C.)
Null hypothesis :
H0 : μ ≤ 12
. The direction of the sign in the alternative hypothesis signifies the type of test or tht opposite direction of the sign in the null hypothesis.
Hence, this is a right tailed test ; Alternative hypothesis, H1 : μ > 12
d.)
If Pvalue is less than or equal to α ; we reject the Null.
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 ;)
Based on the given problem of -7x⁴ = 36, the solution to the equation is x = -1.5.
<h3>What is the solution to this problem?</h3>
The equation to find x is given as:
-7x⁴ = 36
Solving it gives:
-7x⁴ = 36
x⁴ = 36/-7
x⁴ = -36/7
x = ⁴√(-36/7)
x = -1.5
In conclusion, x is -1.5.
