1. Compute the value of tc
needed for a confidence level of 99% with a sample size of 12. Round your answer to 5 decimal places.
2. Compute the value of tc
needed for a confidence level of 95% with a sample size of 33. Round your answer to 5 decimal places.
3. Compute the value of
t
c
needed for a confidence level of 90% with a sample size of 6. Round your answer to 5 decimal places.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
