Answer & explanation:
A confidence interval is an estimated range of a parameter of interest. Confidence intervals are used to indicate the reliability of an estimate. For example, a confidence interval can be used to describe how reliable a search result is.
In other words, a high confidence interval Z value implies that a survey is more likely to indicate the actual values being presented.
In biostatistics, for example, the Z value can be used in calculations to assess the prevalence of a particular disease and the factors associated with it in a population.
The value of Z, however, is not used as a percentage (like the 99.5% addressed in this question) for calculations. A universal table is used to convert Z values and use them in statistical calculations.
Some examples of Z value conversions can be found in the table attached in this question.

Answer
The statement that describes the mountains in Alaska as shown in the image is these mountains likely formed from compression
Explanation
The mountains can be described to form from contrasting units of fractured rocks. The fractured rocks movement along the fault of Denali created an uplift of the ranges that form and bend at the fault line. Tectonic movement that occurred in the fault caused earthquake events that created the asymmetric pattern along the fault.
Answer:
a) 1 tall:1 dwarf
Explanation:
Let's assume that the allele T is responsible for tallness while the allele "t" imparts dwarfism. The genotype of a homozygous recessive dwarf pea plant is "tt" and that of the heterozygous tall pea plant is "Tt". The heterozygous tall parent would make two types of gametes in equal proportion while the homozygous parent would produce all the gametes carrying "t" allele only.
A cross between Tt and tt gives progeny in following phenotype ratio= 1 tall: 1 dwarf.
