Question

Is there a baby season? Or does every season have the same number of babies born each season? The table below shows the number of babies, from 952 that were looked at, that were born in each season. Complete the rest of the table by filling in the expected frequencies:

Frequencies of Babies Born in Each Season

Outcome	Frequency	Expected Frequency
Winter	232
Spring	221
Summer	289
Fall	210

R vector data: 232,221,289,210
Excel data

Expected Frequency for Winter

Expected Frequency for Spring  

Expected Frequency for Summer

Expected Frequency for Fall

Answer 1

In this we need to find the expected frequencies

The expected frequencies are supported by the claim that same number of babies are born each season

So out oof total of 952 babies if we expect same number of babies to be born each season then the number of babies each season would be 952/4=238.

So the table is as follows

Outcome	Frequency	Expected Frequency
Winter	232	238
Spring	221	238
Summer	289	238
Fall	210	238

Hence above table gives all the expected frequencies.

Do comment if you have any doubt.
