Securing a Promotion in the Real World Students graduating from college often worry about their performance in the real world, doing real tasks in real jobs. One big concern is that their lack of hands on experience might hurt their ability to secure promotions. A survey asked students in their first job out of college how long it took to secure their first promotion. Answers are available in the promotions tab of the excel file. Please answer the following questions.

1. How many respondents were promoted within 3 months or less?

2. How many respondents took 8 months or more to get promoted ?

3. How many respondents were promoted between 5 and 7 months ?

4. How many respondents were promoted between 3.4 and 4.6 months ?
