The histogram shows Julia’s monthly deposits into her savings account from January to September
Julia's Monthly deposit in the month of June is $250, in the month of July is in between $300 to $350 and for the month of August it is $300
So , there is no gap in these months.
Further, frequency is not low rather it is on the higher side in June, July & August.
Deposits in these 3 months are not symmetric as deposits are very high in these months as compared to other months.
There is a cluster in June, July and August which is clearly visible in the histogram itself. So the correct answer is there is a cluster in June, July and August.
Hope this helps..!!
