If the true population proportion of children with an oral cleft whose mothers smoked is as low as 0.25, you want to risk only a 10% chance of failing to reject the null hypothesis. if you are conducting a two-sided test at the 0.01 level of significance, how large a sample would be required?

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

won't that be plagrisim thought?

step-by-step explanation:

step-by-step explanation: 2

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
