Question:

Consider that 30% of the understudies of a given class are occupied with project during the thirteenth seven day stretch of semester. In addition, accept that 22% of understudies are female, and 18% of all understudies are females who occupied with project during the thirteenth seven day stretch of semester.

On the off chance that you pick an understudy aimlessly from this scholarly community, what is the likelihood that this individual is a male who take part in project during the thirteenth seven day stretch of semester?

In the event that you pick an understudy indiscriminately from this scholarly world, what is the likelihood that this individual is a male who doesn't take part in project during the thirteenth seven day stretch of semester?

An analyst leads an investigation to comprehend the connection between estriol level in pregnant ladies and the birth weight of their infants. The scientist gathers an example of 100 kids. The example mean birth weight is =3, with test standard blunder S = 1.7

Structure a 95% and 99% certainty span for the genuine mean birth weight

A baby is considered 'underweight' if their introduction to the world weight is beneath than 1.8. Test the invalid speculation that the genuine mean is 1.8 against the elective theory that the genuine mean is under 1.8. Process a Z-score. What do you finish up?

3.True or bogus (and why): the p-esteem is the likelihood that the speculation is valid.

Whatis the main huge change that American drivers made because of higher gas costs? As per an Access America overview, 30% said that it was cutting sporting driving.

In any case. 27% said that it was solidifying or diminishing tasks. In the event that these figures are valid for all American drivers, and If 20 such drivers are arbitrarily examined and asked what Is the primary huge change they made because of higher gas costs,

Whatis the likelihood that precisely 8 said that it was solidifying or diminishing tasks?

Whatis the likelihood that none of them said that It was cutting sporting

driving?

What is the likelihood that in excess of 7 said that it was cutting sporting driving?

At a home loan organization, 60% of calls are replied by a chaperon. The

staying 40% of guests leave their telephone numbers. Of these 40%, 75%

get a return call that very day. The excess 25% get a

return call the following day.

Of the individuals who at first addressed an orderly, 80% will apply for a home loan.

Of the individuals who got a return call that very day, 60% will apply. Of those

who got a return call the following day, 40% will apply.

Compute the likelihood that an individual at first addressed a chaperon, given

that the person in question applied for a home loan.

10. The purpose of hypothesis testing is to: (a) Determine value of the sample mean. (b) Determine evidence in favor of a parameter. (c) Determine the appropriate value of test statistic. (d) Derive the standard error of the data. Answer= 11. Chebyshev's Theorem states that the percentage of measurements in a data set that fall within two standard deviations of their mean is: *) 75% b) At least 75% ) 88.89% d) At least 88.89%. Answer= 12. Normally distributed data are referred to as: ") Bell-shaped b) Asymmetrical Skewed d) Peaked Answer= 13. What is the correct decision in a hypothesis if the data produce a t-statistic that is in the critical region? .) Reject He ) Fail to reject Ho
