Serum cholesterol levels of 100 hypertensive patients were recorded. Mean cholesterol level was 190 mg/d1. The data was symmetri
xxTIMURxx [149]

The standard error is 1.5.

The range of 95% confidence interval is 160 mg/dL and 220 mg/dL

<h3>What is the standard error of the distribution?</h3>

The standard error of the distribution is calculated as follows:

  • Standard error = standard deviation/√N

where N is the number of participants = 100

From the empirical rule of a normal or symmetrical distribution;

  • 68% of the data lies within one standard deviation
  • 95% percent within two standard deviations, and
  • 99.7% within three standard deviations from the mean.

Therefore,  175 mg/dl and 205 mg/dl lie one standard deviation from the mean.

One standard deviation = 175 - 190 or 205 - 190 = ±15

Standard deviation = 15

a. Solving for the standard error using the equation above;

Standard error = 15/√100

Standard error = 1.5

b. The range of 95% confidence interval is two standard deviations away from the mean.

Range of values two standard deviations from the mean = 190 - (2*15) and 190 + (2 * 15)

Range of values two standard deviations from the mean = 160 mg/dL and 220 mg/dL

Therefore, the range of 95% confidence interval is 160 mg/dL and 220 mg/dL

In conclusion, the standard error is calculated from the standard deviation and the sample size.

Word Bank for #4-8: Read the passage and fill in the blanks using the following terms.
snow_tiger [21]

Answer:

<h2>option d Meiosis</h2>

Explanation:

Term Meaning

Gamete A sex cell (in humans: sperm for males, and eggs for females)

Meiosis A two-step process of cell division that is used to make gametes (sex cells)

Crossing over Process in which homologous chromosomes trade parts

Interphase Phase of the cell cycle where the cell grows and makes a copy of its DNA

Homologous chromosomes Set of chromosomes (one from each parent), that are very similar to one another and have the same size/shape

Sister chromatids Two halves of a duplicated chromosome

Diploid (2n) Cell that contains two sets of homologous chromosomes

Haploid (n) Cell that contains only a single set of genes

Meiosis

The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).

Stages of meiosis

Meiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
