It is probable that the question should read:
Whats does PLIP mean on (or with respect to) Peugeot 307?
and in that case the PLIP is the remote key-fob that operates the car's central locking. So named for the 'plip!' sound the car make when the lock is opened or closed.

What is the standard deviation and what is the probability that a student scored higher than 322 if the mean test score is 312 and 16 percent of the scores are under 307?
Assuming a normal distribution: If 16% are less than 307, then 84% are greater than 307. Using single tailed normal tables we want the z value which gives 84%-50% = 34% = 0.34 to the left of the mean; this is z ≈ -0.995 z = (value - mean)/standard deviation → standard deviation = (value - mean)/z ≈ (307 - 312)/-0.995 ≈ 5.03 The z value of 322 is z ≈ (322 - 312)/5.03 ≈ 1.99 Using the single tailed tables give the value of the normal distribution for z = 1.99 as approx 0.477 to the right of the mean. This means that 0.477 + 0.5 = 0.977 are less than 322 → 1 - 0.977 = 0.023 = 2.3 % are greater than 322 → probability greater than 322 is 2.3%
What does mean mean in statistics?
Mean is the average.
What is a sentence using the word mean?
I didn't mean what I said. What does antidisestablishmentarianism mean? My sister is mean. I don't like being mean. The mean of a set of values is the average. The mean temperature is much lower in the valley in spring.
What is population mean in statistics?
The population mean is the mean value of the entire population. Contrast this with sample mean, which is the mean value of a sample of the population.
What is standard deviation of the mean?
If repeated samples are taken from a population, then they will not have the same mean each time. The mean itself will have some distribution. This will have the same mean as the population mean and the standard deviation of this statistic is the standard deviation of the mean.
