In their advertisements, the manufacturers of a diet pill claims that taken daily, their pill will produce an average weight loss of 10 pounds in one month, with standard deviation 3 pounds. In order to determine if this is a valid claim, an independent testing agency selects 36 people to take the pill daily for a month and found the mean weight loss for this group was 9 pounds.
Does this indicate at a 5% level that the mean weight loss is less than 10 pounds?
What are the null and alternative hypotheses?
Select one:
a. H0: μ = 10 and HA: μ < 10
b. H0: μ = 0.05 and HA: μ < 0.05
c. H0: μ = 10 and HA: μ > 10
d. H0: μ = 10 and HA: μ = 9

H0: μ = 10 and HA: μ < 10

Step-by-step explanation:

The population mean, μ = 10

The null hypothesis takes the value of population mean as the initial truth ; hence, the Null hypothesis will take the mean weight value as 10 ;

H0 : μ = 10

The alternative hypothesis is tested using samples which are meant to counter the stance of the null hypothesis ; since we are to test if the mean value is less than the Null ;

The alternative hypothesis becomes ;

H1 : μ < 10

this is not the answer this is just a question. is this middle school math?

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.
