error whereby, the null hypothesis is not rejected yet it is false (Taylor, 2012). This type of error is usually controlled by the level of significance chosen. By choosing a 0.05 confidence level means that the chance of going for the false null hypothesis is 5% whereas, by choosing a 0.01 level of significance, that probability reduces to 1%. 3) a.) Yes, it exceeds 3.0. b.) Mean for enjoying nature exceeds 3.5. c.) Preference for outdoor experience is same for both males and female. d.) The importance attached to v2 and v6 is not the same. e.)

error is an unintended action or decision.We are all prone to making errors regardless of the training one has because human error is inevitable, however, much a person may be smart. The way that a brain responds to and processes information may negatively affect the performance of a nurse such as medication administration. It is one of the human factor issues that has been identified. Such errors have proven to be very costly hence the need to address factors that influence behavior in ways health and safety are affected. Human errors often occur due to lack of proper training before engaging in a particular task resulting in them making wrong decisions that they believe to be right (Reddy, 2016)....

error. Bradford assay also produced higher values for protein. Errors during the experiment could be caused by poor mixing. The exercise has confirmed that the two reliable ways of measuring protein concentration. The standard deviation also indicates that better controls should be incorporated into the experiment.

Type I Error And Type II Error

0
(0)

Error And Type II Error Name Institution Type I Error And Type II Error Type I error is also called a false positive which is the error of rejecting a null hypothesis when in fact it is true. False positive can also be described as accepting the alternative hypothesis when the findings are as a result of chance. A type I error takes place when one sees a statistically significant difference when in reality there is no difference. The likelihood of creating a type I error in a test with rejection region R is P (R | H0 is correct) (Mertler & Reinhart, 2016). On the other hand, type II error is called a false negative which is the error of accepting a null hypothesis when in fact it is false. A...

errors that may affect the realization of the desired results. A large pea plant farm is required while conducting the study, which should grow and mature in one season. The plants must be true breeding plants with a pair of traits each: dwarf plants with constricted pods and tall plants with inflated pods. It is important to note that the traits will be sorted independently; thus, resulting in a ratio of 3:1 for the 1st progeny and 9:3:3:1 for the subsequent progeny. Two pure breeds’ parental pea plants were crossed, which resulted in tall F1 offspring with inflated pods. The results indicated that the traits for tallness and inflated pods are dominant over the dwarf and constricted pods, which...
