The solution of the inequality is x < -9
<h3>How to solve the inequality for x?</h3>
The inequality expression is given as:
-11 < -18- 7/9x
Add 18 to both sides of the inequality
18 - 11 <- 7/9x
Evaluate the difference
7 <- 7/9x
Multiply both sides by -9/7
-9 < x
Rewrite as:
x < -9
Hence, the solution of the inequality is x < -9

Solution :
The null and alternative hypothesis is given by
Assume that the level of significance, α = 0.05
The t-test statistics is, t = 1.484
Degree of freedom :
df = n - 1
= 14 - 1
= 13
The P-value is given by
P-value = 2P (T>|t|)
= 2P(T>|1.484|)
= 2P(T>1.484)
= 2(=T.DIST.RT(1.484,13))
= 0.05
