You are constructing a 95% confidence interval of a sample space consisting of n = 40 values and a
population standard deviation of 2.6. the population appears to be skewed. determine whether a
margin of error should be calculated using a critical value of za/2, a critical value of ta/2, or neither.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

the answer to the expression is 83

the answer is 3/2 and for decimal: 1.5
