Answer:
9/16
Step-by-step explanation:
Next time write the mixed number like this:
1 1/3 just so you know so ppl can answer it better
Confidence interval is given by the formula
x ⁺/₋ z* ( σ/ (√n) )
Where:
x = the sample mean = 130
z* = the z-value for 90% confidence = 1.645
σ = standard deviaton = 7
n = sample size = 145
Substituting these values into the formula gives:
130 ⁺/₋
130 ⁺/₋ 0.956
So the interval is in between (130 - 0.956) and (130 + 0.956)
