12 temperature measurements are made in a laboratory over a period of time and the following values are obtained: 46,45,45,47,48,49,50,52,51,51,14,36 Use Chauvenet's criterion to identify any outliers in the data which should be rejected. Don't use the chauvenets table. Use the normal distribution table.

4.7, 5.0, 5.5, 4.2, 5.5, 5.9, 4.7, 5.4, 3.8 - samples of % peroxide in samples taken. determine the interquartile range, variance, and standard deviation of the percent peroxide data. use 2 decimal points for rounding and provide units

for normal distribution mean is 50 liter per hour and standard deviation is 10 liter per hours . find the 68%,95%and 99.7% values by using emperical graph  explain graph with all values

Find the proportion of Normally distributed observations with a z-score above 0.80. Give your answer to four decimal places. Find the proportion of N.d. observations with a z-score between z1​= -0.34 and z2​= 2.72. Give your answer to four decimal places.

Assume the samples are random and independent, the populations are nomally distributed, and the population variances are equal. The table available below shows the prices (in dollars) for a sample of automobile batteries. The prices are classified according to battery type. At a = 0.10, is there enough evidence conclude that at least one mean battery price is different from the others? Complete parts (a) through (e) below. E Click the icon to view the battery cost data. (a) Let u1. P2. H3 represent the mean prices for the group size 35, 65, and 24/24F respectively. Identify the claim and state Ho and H. H Cost of batteries by type The claim is the V hypothesis.

Assume that IQ scores follow a Normal distribution with µ=100 and σ=16.  Using our IQR rule for determining IQ score outliers, what IQ scores would establish the lower and upper fences for determining outliers?

Describe the importnat features of the distribution by identifying the mode, overall shape, and outliers. a. Which measure of center (mean or median) and which measure of variability (Standard deviation or IQR) would be best to describe the distrubution and why?

Acorns in the northern Atlantic regions of the U. S. have an average volume of 3.75 cubic centimeters, with a standard deviation of .85 centimeters. If we were to collect 1000 samples of 300 randomly-selected acorns, describe the sampling distribution for the sample mean of acorn volumes. Round to the nearest hundredth (two decimal places) if necessary. Shape: Center: Spread:
