How can we convert 75 percentile into percent?

You cannot. The 75th percentile is the value of a variable such that 75% of the observations are below that value and 25% are higher. The 75th percentile in the heights of adult women will be a measure of height whereas the 75th percentile in the income distribution in a country will be the level of income [in some currency unit] such that 75% of incomes in the country are lower. These examples illustrate that the 75th percentile can be a measurement in any unit and converting to a percentage makes no sense.


What is the formula to convert a z score into a percentile rank?

You need to look up z-score tables.


What is the percentile rank if the raw score is 34?

It is not possible to convert a raw score into a percentile without knowing the distribution of scores and key parameters of the distribution. Since none of this information is provided, it is not possible to give a sensible answer.


What is the fifth and 9fifth percentiles of a mean temperature of 98.2 and the standard deviation is 0.62?

The 5th percentile of a standard normal distribution is -1.645 (from the normal probability table). z = (x - &mu;) / &sigma; -1.645 = (x-98.2) / .62 (0.62)(-1.645) = x-98.2 -1.0199 = x-98.2 x = 98.2-1.0199 = 97.1801 The 5th percentile is 97.18 The 95th percentile of a standard normal distribution is 1.645 (from the normal probability table). z = (x - &mu;) / &sigma; 1.645 = (x-98.2) / .62 (0.62)(1.645) = x-98.2 1.0199 = x-98.2 x = 98.2+1.0199 = 99.2199 The 95th percentile is 99.22
