Jamie get's $10,000 dollars added onto her annual paycheck after 10 years.
Wei on the other hand, get's $15,000 dollars added onto his annual paycheck after 10 years.
Jamie's total: $35,000
Wei's total: $34,000
So Jamie would have a better pay than Wei for 10 years, but after that Wei will take the lead.
Since the person had $408.98 to begin with and took away/withdrawal ($178.67+$100=$278.67) $278.67 and then added/deposited $214.87....
$408.98-$278.67+$214.87=$345.18
Answer:
a) Between 74 and 90
b) 81.86% of the scores are between 78 and 90
Step-by-step explanation:
a) According to the Empirical Rule, in a normal distribution, 95% of the data are within 2 standard deviations of the mean. Therefore, the range that 95% of the scores fall in is between 82-4(2)=74 and 82+4(2)=90.
b) The percent of scores that are between 78 and 90 is: normalcdf(lower,upper,μ,σ) = normalcdf(78,90,82,4) = 0.8185946784 ≈ 0.8186, or about 81.86% of the scores.
