Answer:
(a) H0: mu = 17 vs. Ha: mu < 17
(b) Sample statistic is 1.6
Explanation:
(a) A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) the upon testing. It is expressed using the equality sign.
An alternate hypothesis is also a statement from a population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
(b) Sample statistic = sample mean ÷ sample size = 16 ÷ 10 = 1.6
Half life is the amount of time for one half of an isotope decay. Strontium-90 under goes a beta decay, which means that it will lose an electron forcing a neutron to turn into a proton. This decay process on Strontium-90 makes it have a half life of 28.8 days.
Answer:
The common element in RNA interference treatment for aids,hepatitis,and cancer include the silencing of gene expression.
Explanation:
- Through the degradation of targeted mRNA, gene silencing is done which is very popular in the eukaryotic organism and it is a highly conserved process.
- In the treatment of aids,hepatitis,and cancer, gene therapy is needed because they cannot be cured by simple consumption of drugs.
- The treatment is carried by silencing the gene expression of the particular mRNA host by utilization of RNA interference (RNAi).
Both animal and plant cells undergo respiration. Although this respiration goes toward different activities (photosynthesis for plants and muscular respiration for animals), both processes intake oxygen and get rid of carbon dioxide as a waste product.
Answer:
It relay signals between the cell internal and external environment.
It allows cell to identify each other and interact.
