In a large human population, cranial length is approximately normally distributed with a mean of 185.6 mm and a standard deviation of 12.7 mm. What is the probability that a random sample of size 10 from this population will have a mean less than than 180? a. 0.0174 b. 0.1357 c. 0.0823 d. -1.39

The correct option is  c

Step-by-step explanation:

From the question we are told that

   The mean is  

   The standard deviation is  

   The sample size is  n = 10  

    Generally the standard error of the mean is mathematically represented as

=>    

=>    

Generally the probability that a random sample of size 10 from this population will have a mean less than than 180 is mathematically represented as

From the z table  the area under the normal curve to the left corresponding to    -1.394  is  

=>

step-by-step explanation:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
