Mean(๐‘ฅ ฬ…) = a + h ร— (โˆ‘โ–’๐’‡๐’Š๐’–๐’Š)/(โˆ‘โ–’๐’‡๐’Š) Where a = Assumed Mean h = Class interval = 550 = 520 โ€“ 500 = 20 Also, โˆ‘โ–’๐’‡๐’Š = 50 โˆ‘โ–’๐’‡๐’Š๐’–๐’Š = โˆ’12 Putting values in formula Mean(๐’™ ฬ…) = a + h ร— (โˆ‘โ–’๐’‡๐’Š๐’–๐’Š)/(โˆ‘โ–’๐’‡๐’Š) ๐‘ฅ ฬ… = 550 + 20 ร— (โˆ’12)/50 ๐‘ฅ ฬ… = 550 โ€“ 4.8 ๐’™ ฬ… = 545.2 Therefore, mean average wage is Rs 545.2
