Answer:
Yes, There is significant difference.
Step-by-step explanation:
Null Hypothesis , H0 : Mean income = 15000
Alternate Hypothesis , H1 : Mean income ≠ 15000
t = (x - u) / ( s / √n)
x = sample mean = 14500 here, u = population mean = 15000 here , s = standard deviation = 975 here , n = sample size
t = (14500 - 15000) / (975 / √169)
-500 / 75 = - 6.66
As calculated t value in absolute terms is > 1.96 , ie tabulated value at 95% significance level (two sided). So we reject the null hypothesis in favor of alternate hypothesis. Hence, we state that 'Mean Income ≠ 15000'

Answer:
a) 2.5 pounds of candy
b) 2.5 pounds of candy
y × 1 = 0.5 × 5
y = 2.5
Step-by-step explanation:
1 = 5
1/2 = y or 0.5 = y
y × 1 = 0.5 × 5
y = 2.5
Notice that
, so
Then taking the positive square root gives
so 
and
