The sample size is n = 23
The sample mean is
The standard deviation is
From the question we are told the confidence level is 80% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the margin of error is mathematically represented as
=>
Generally 80% confidence interval is mathematically represented as
=>
Y = 2x + 3
Would be the answer with 2 being the slope and 3 being the y-intercept
John's gross monthly salary is $2000.
John receives a 15% raise in his salary.
So first we have to find 15% of $2000.
15% of 2000 =
=
=
=
John's salary including the raise = $ = $2300.

30% of 2300 =
=
=
=
So the amount of tax deducted = $690.
John's net monthly income = $ = $1610.
