Can someone show me the written work so I can have a breed understanding please?

Age discrimination: The following table presents the numbers of employees, by age group, who were promoted, or not promoted, in a sample drawn from a certain industry during the past year, Age Under 30 30-39 40-49 50 and Over Promoted 17 23 22 15 Not promoted 48 29 49 33 Send data to Excel Can you conclude that the people in some age groups are more likely to be promoted than those in other age groups? Use Excel and the a = 0.10 level of significance. We do not reject the null hypothesis. There is not enough evidence at the a = 0.10 level of significance to say that people in some age groups are more likely to be promoted
