Heights of 130 singers in the NY Choral Society in 1979 were self-reported tothe nearest inch. The four voice parts in order from highest pitch to lowest pitchare Soprano, Alto, Tenor, Bass. The first two are female voices and the last twoare male voices. We would like to test if different parts have significantlydifferent heights.The standard deviations are: s1=2.8 s2=2.4 S3=1.9 s4-3.2Using the equal variance assumption, can we say the standard deviations areclose enough to use ANOVA? (select all that apply)O The assumption is not violatedO We can use ANOVAO The assumption is violatedO We should NOT use ANOVÁ

The objective is to choose applicable option to use assumption of equal variances about SD is close…

In the 1992 presidential election, Alaska's 40 election districts averaged 1980 votes per district for President Clinton. The standard deviation was 573. (There are only 40 election districts in Alaska.) The distribution of the votes per district for President Clinton was bell-shaped. Let X = number of votes for President Clinton for an election district. (Source: The World Almanac and Book of Facts) Round all answers except part e. to 4 decimal places.PLEASE ANSWER C, D AND E AND ROUND TO THE 4 DECIMALc. Find the probability that a randomly selected district had fewer than 2062 votes for President Clinton. d. Find the probability that a randomly selected district had between 2052 and 2347 votes for President Clinton. e. Find the first quartile for votes for President Clinton. Round your answer to the nearest whole number.

A mechanic sells a brand of automobile tire that has a life expectancy that is normally distributed, with a mean life of 35,000 miles and a standard deviation of 2100 miles. He wants to give a guarantee for free replacement of tires that don't wear well. How should he word his guarantee if he is willing to replace approximately 10% of the tires? Click to view page 1 of the table. Click to view page 2 of the table. Tires that wear out by miles will be replaced free of charge. (Round to the nearest mile as needed.)
