Answer: t= -1.60
Explanation:
Let
be the population mean weight of pigs.
As per given , we have


Sample size : n= 16
Sample mean =
Sample standard deviation : 
<em>Since the population standard deviation is not known so the test is a</em><em> t-test.</em>
Test statistic for population mean : 
(Substitute all the values.)
Hence, the value of the test statistic needed to test the null hypothesis : t= -1.60
Answer:A
Explanation:
The weakness of scatterplots is that they, do not actually quantify the relationships between variables.
The factors which determine the shape of protein are;
1. Order of amino acids.
2. The number of amino acids which are used.
The order of amino acids or in other words primary structure determines how folding of amino acid chain or its tertiary structure.
Protein is termed as the chemicals which are found in all cells which are used for growth and work. Protein in the human body includes hemoglobin and collagen.
