The nice thing about sampling is that the only possible problem you have is that you might pull the wrong item. for example, maybe you were supposed to pull item number 97 for testing, and instead you pulled item 79, or item 96. but once you pull the correct sample, there are no more problems." required: do you agree or disagree with the preceding material? why? 67

I disagree

Step-by-step explanation: there are other types of errors associated with sampling

Systematic errors,Gross errors and Random errors.

Systematic errors are errors due to observation, measurement etc

Gross errors are errors due to improper input or computation of values as the question highlights.

Random errors are errors inherent in equipment where different results are obtained using the same equipment.

The error observed in the question is a Gross error where the value entered is wrong.

where is the figure

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
