The mean of 40 observations was 160. It was detected on rechecking that the salue of
Ierofanga [76]

Answer: The correct mean is 161.

Step-by-step explanation: The question states that we have computed the mean of 40 observations and the mean is 160. This means the set of data altogether is 40 numbers. In order to arrive at the mean, we must have added all 40 observed data to get the summation of observed data and divided this by 40. In other words, we must have done something like,

Mean = {Summation} x/{x}

Where x = 40 and the mean computed is 160.

Therefore,

160 = {summation}x/40

By cross multiplication we now have

160 (40) = {summation} x

6400 = {summation}x.

However, we must not forget that one of the values in the observed data was wrongly copied as 125, (instead of 165). What this means is that the summation of all observed data is having a shortage of 40 (that is, 165 - 125). If we now insert the correct figure of 165 in place of the wrong one which is 125, our summation of observed data would now become 6440 (the shortage of 40 would have been added back to 6400).

What we now have is

Mean = {summation}x/x

Mean = 6440/40

Mean = 161

2. George estimates that each bale of hay in his field weighs 62.5 pounds on
saw5 [17]

Answer:

4 trips

Step-by-step explanation:

there are 892 bales of hay

each one weighs about 62.5 pounds

892 * 62.5 = 55,750

George's truck can only carry 8 tons

1 ton = 2,000 pounds

2,000 * 8 = 16,000 pounds

So,

55,750 / 16,000 = 3.484375

But since you can't make 3.484375 trips in a truck, round it up.

3.484375 rounded up equals 4

George has to take 4 trips
