One standard deviation

Because as the sample size increases the Student's t-distribution approaches the standard normal.

The total area under a normal distribution is not infinite. The total area under a normal distribution is a continuous value between any 2 given values. The function of a normal distribution is actually defined such that it must have a fixed value. For the "standard normal distribution" where μ=0 and σ=1, the area under the curve is equal to 1.

Yes.

You calculate the standard error using the data.

The standard normal distribution is a subset of a normal distribution. It has the properties of mean equal to zero and a standard deviation equal to one. There is only one standard normal distribution and no others so it could be considered the "perfect" one.

One standard deviation

The mean, median, and mode of a normal distribution are equal; in this case, 22. The standard deviation has no bearing on this question.

Only the mean, because a normal distribution has a standard deviation equal to the square root of the mean.

Because as the sample size increases the Student's t-distribution approaches the standard normal.

The answer will depend on the underlying distribution for the variable. You may not simply assume that the distribution is normal.

false

-1.43 (approx)

z = 1.52 (approx)

Yes, mode equals median in a normal distribution.

Yes, it is true; and the 2 quantities that describe a normal distribution are mean and standard deviation.
