2. Swapna gathered data on the number of page views for each of her blog posts .For her 40 latest posts, she found a sample mean of 358 with a population standard deviation of 54.3 .What is the approximate 95% confidence interval for her page views?

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
